CPP: Structure

Hi, CPP Programmer, welcome.

Structure vs array

Structure are different types value. Array are the same type value.

Structure consist of:
1. Structure variable
2. Structure tag
3. Structure member

Defining structure tag is optional.
Defining member is just like the defining variable.

Basic structure use are below:
#include <iostream>
#include <cstring>

using namespace std;

//1.Create the structure
struct Books{
char title[50];
char author[50];
char subject[50];
int book_id;
};



int main()
{
//2. Declare Book1 of type Books
struct Books Book1;
struct Books Book2;


//3. Define book Book1 specification
strcpy( Book1.title, "Learn C++ Programming");
strcpy( Book1.author, "Chand Miyan");
strcpy( Book1.subject, "C++ Programming");
Book1.book_id = 6495407;

//4. Define book Book2 specification
strcpy( Book1.title, "Telecom Billing");
strcpy( Book2.author, "Yakit Singha");
strcpy( Book2.subject, "Telecom");
Book2.book_id = 6495700;

//5. Print out Book1 info
cout << "Book 1 title: " << Book1.title << endl;
cout << "Book 1 author: " << Book1.author << endl;
cout << "Book 1 subject: " << Book1.subject << endl;
cout << "Book 1 book id: " << Book1.book_id << endl;

//6. Print
cout << "Book 1 title: " << Book1.title << endl;
cout << "Book 1 author: " << Book1.author << endl;
cout << "Book 1 subject: " << Book1.subject << endl;
cout << "Book 1 book id: " << Book1.book_id << endl;

}

Sending structure variable pointer to a function is almost the same as sending the struct variable to the function, the difference is: if you use structure variable pointer you use asterix and you need to declare a structure variable pointer.

SMALL BASIC: Printing stars

Hi, SMALL BASIC programmer, welcome.

In this tutorial, we will discus about variety of printing stars or asteriks.
1. Incremented stars
num_of_row = 10
For i = 0 To num_of_row
  For j = 0 To i
    TextWindow.Write("* ")
  EndFor
  TextWindow.WriteLine("")
EndFor

Output:

2. Reversed incremented (decremented stars)
num_of_row = 10
For i = num_of_row To 0 Step -1
  For j = 0 To i
    TextWindow.Write("* ")
  EndFor
  TextWindow.WriteLine("")
EndFor


 

Or, you can combine step 1 and step 2 into one program, like below:

num_of_row = 10

For round = 0 To 100

For i = 0 To num_of_row

  For j = 0 To i

    TextWindow.Write("* ")

  EndFor

  TextWindow.WriteLine("")

EndFor

'TextWindow.WriteLine("Ok, sukses atas")

Program.delay(1000)

TextWindow.Clear()

For i = num_of_row To 0 Step -1

  For j = 0 To i

    TextWindow.Write("* ")

  EndFor

  TextWindow.WriteLine("")

EndFor

Program.Delay(1000)

TextWindow.Clear()

EndFor

3. The decremented space

num_of_row = 10

For i = 1 To num_of_row

  For j = 1 To num_of_row - i 

    TextWindow.Write("  ")

  EndFor

  For k = 1 To i

    TextWindow.Write("* ")

  EndFor

  TextWindow.WriteLine(" ")

EndFor

Output:

4. The last the increment space

num_of_row = 10

For i = 1 To num_of_row 

  For j = 1 To i

    TextWindow.Write("  ")

  EndFor

  For k = 1 To num_of_row - i 'the rest of colomn

    TextWindow.Write("* ")

  EndFor

  TextWindow.WriteLine(" ")

EndFor

Output:

5. The last, I don't know what to call this, but I call this cool stars

num_of_row = 10

For i = 1 To num_of_row

  For j = 1 To num_of_row - i 

    TextWindow.Write("  ")

  EndFor

  For k = 1 To num_of_row - 1

    TextWindow.Write("* ")

  EndFor

  TextWindow.WriteLine(" ")

EndFor

6. I don't know what to call this, but I call this smooky stars

num_of_row = 10

For i = 1 To num_of_row

  For j = 1 To num_of_row - i 

    TextWindow.Write("  ")

  EndFor

  For k = 1 To j

    TextWindow.Write("* ")

  EndFor

  TextWindow.WriteLine(" ")

EndFor

Journey to find Gog and Magog

Fact
1. Gog and magog mentioned twice in the bible:

Ezekiel 38:2

“Son of man, set your face against Gog, of the land of Magog, the chief prince of Meshek and Tubal; prophesy against him

In Context | Full Chapter | Other Translations

Revelation 20:8

and will go out to deceive the nations in the four corners of the earth—Gog and Magog—and to gather them for battle. In number they are like the sand on the seashore.

2. Ezekiel prophet was born 621 BC. Live in the ancient Israel.

3. Babylonian Kingdom exist in the time Ezekiel mentioned Gog and Magog

4. First world map is from Babylonian 600 B.C. according to Wikipedia: https://en.wikipedia.org/wiki/Early_world_maps

IPv4 Activity

Basic:
1. Binary to decimal conversion activity
For example:
Enter the decimal of this binary: 00110111
Decimal is: 55

2. Decimal to binary conversion activity
For example:
Enter the binary of this decimal: 241
The binary is: 11110001

3. Given address/prefix 144.97.144.28/23
Determine:
1. Network address,
1.1. Last octet in binary
1.2 Last octet in decimal
1.3 Enter full address in decimal

2. Broadcast address
2.1 Last octet in binary
2.2 Last octet in decimal
2.3 Enter full address in decimal

3. First usable host address
3.1 Enter last octet in binary
3.2 Enter last octet in decimal
3.3 Enter the full address in decimal

4. Last Usable Host Address
4.1 Enter Last octet in binary
4.2 Enter Last octet in decimal
4.3 Enter full address in decimal





To remember this: NAHAMA.

NA = Network address
HA = Host Address
FHA = First host address
LHA = Last host address
HBA = Host Broadcast Address
SMA = Subnet Mask Address


1. Determining network address in decimal and in binary of a pair host address and mask address.

For example:
Host address: 10.158.30.81
Subnet Mask: 255.255.224.0


Solution: Anding both each host octet and respective subnetmask octet.

You can watch how the solution is in this video:

2. Determining the number of host

The solution is: (2 ^ number of bit 0 in the subnetmask in binary form) - 2.

You can watch how to solve it easily in this video:

3. Determining First Usable Host (FUH), Last Usable Host (LUH), Broadcast address in Decimal (BAD), and Next Network in decimal (NND)

First Usable Host (FUH)
1. Get all bit 0 in subnetmask in binary
2. Increment 1 to last octet.

Last Usable Host (LUH)
1. Get all the 0 bits of subnetmask in binary.
2. Make 1 all except the Less Significant bit (LSB).
3. Divide the bits of step 2 per octet.
4. Increment each octet value to each octet of network address in decimal.

Broadcast address in Decimal
1. Get all the 0 bits subnetmask in binary
2. Make 1 all
3. Divide the bits of step 2 per octet
4. Increment each octet value to each octet of network address in decimal.

Next Network in decimal (NND)

SMALL BASIC: Factorial Calculator

Hi, SMALL Basic programmer, welcome.

Did you know, we can also make factorial calculator using SMALL BASIC?

We will divide the code as:
1. Code with wrong result of  0!
2. Code that with correct result of 0!
So, you can see the difference.

Below is the code:

1. Code with wrong result of 0!
TextWindow.WriteLine("Welcome to factorial calculator")
TextWindow.WriteLine("Enter the n: " )
n = TextWindow.Read()
res = n
For i = n-1 To 1 Step -1
  res = res * i
EndFor

TextWindow.WriteLine(res)


2. Code with correct result of 0!
This below is completed program:

TextWindow.WriteLine("Welcome to factorial calculator.")
TextWindow.WriteLine("Enter the n: " )
n = TextWindow.Read()
res = n

If n = 0 Then
  res = 1
Else
 
For i = n-1 To 1 Step -1
  res = res * i
EndFor
EndIf

TextWindow.WriteLine("The result of permutation is: " + res)

SMALL BASIC: Programming question session 2

1. If you have an array like below, what is the length of the array, notice the index 0 of the array is empty or "", i.e. What is the output of textwindow window?

myarr[0] = ""
myarr[1] = "A"
myarr[2] = "B"
TextWindow.WriteLine(Array.GetItemCount(myarr))

A). 1 B). 2 C). 3

2. Still with code from number  1


3. Logic question: Mr. Bono told to record all the room number that are not empty and handed that record to Mr. Bing, because Mr. Bing wants to knock every door's room, meet and invite every room user to have a tea while talk with him/her about the rise of the rent.

But,

4). Look for the code below, I want to add fgd array's element to nbr array's element. Do you think the nbr array elements grows or appended with fgd elements forever?

fgd[0] = "Added"
fgd[1] = "Added"
nbr[0] = 0
nbr[1] = 1

start:

nbr_l = array.GetItemCount(nbr)
TextWindow.WriteLine(nbr_l)
TextWindow.Pause()
For i= 0 To 1
  nbr[i+nbr_l] = fgd[i]
EndFor
TextWindow.writeline(nbr)
Program.delay(1000)
Goto start


5). Multi dimension array question. Look at for the code below, do you think the code will generated y as a multi dimension array? or not?

x[0] = 10
x[1] = 11

For i = 0 To 1
  y[i] = x
EndFor


TextWindow.WriteLine(y)
 

6). Still based on question 5, how many lines or rows, array y have?

SMALL BASIC: Interrelation of arrays

Hello, SMALL BASIC programmer, welcome.

In this tutorial we will learned about interrelation of arrays. There are two, three or even more arrays that are interelated during the programming session.

What interrelation of arrays. Interrelation of arrays, I mean what

Use this the value of each of the element's of this array (Array A) to get


1. Get the index of this value
2. Get the value of this index

1. Save as the value of this index
2. Save as the index of this value

So for example, get the index of this value and save it as the value

Get the value of the these indexes and use it as index of to access another array and save it as the value of this index.

SMALL BASIC: Adding or appending elements to array

Hello, SMALL BASIC programmer, welcome.

In this tutorial we will learn how to adding or appending elements to an array. These are few tips or few methods:

1. Adding or appending elements one by one

2. Adding or appending elements one array by one array whole

So, lets discuss this one by one:

1. Adding or appending elements one by one

object_1[0] = "A"
object_1[1] = "B"
object_2[0] = 1
object_2[1] = 2

'Appending one element after one element to an array
'1st. Find the length adder and the length of addee, but
'except the object_1 don't substract it with 1
object_2_l = Array.GetItemCount(object_2) - 1
object_1_l = Array.GetItemCount(object_1)

For i = 0 To object_2_l
  object_1[object_1_l+i] = object_2[i]
EndFor


'2. Get the length of the new object
object_1_l = Array.GetItemCount(object_1)
For i = 0 To object_1_l - 1
  TextWindow.WriteLine(object_1[i])
EndFor
  

SMALL BASIC: Programming questions session 1

3. Still using program number 1, but with slight modification. Is it i incremented each time i is printed out to the textwindow window?

Up:
i = i + 1
TextWindow.WriteLine(i)
For i = 0 To 10
  Goto up
  Program.Delay(1000)
EndFor

4. Still using program number 1, but with slight modification. Is it "Hello World" string printed out to the screen?

Up:
i = i + 1
TextWindow.WriteLine(i)
For i = 0 To 10
  Goto up
  TextWindow.WriteLine("Hello World")
EndFor

Ok, thats it. I hope you enjoy the questions.

SMALL BASIC: Folder-subfolder iteration

Hello, SMALL BASIC programmer, welcome.

In this tutorial, we will learn about how to get all folders and all sub folders started from our first folder or first door.

This tutorial implements tree diagram traversing algorithm.

There are two types of how to draw a tree diagram:
1. Using vertex,vertex label, link, and link label.
2. Using hierarchy

You can train a lot with tree diagram with folder-subfolder iteration. Yeah, you can learn a lot with folder-subfolder.

You can also implement this to full mesh topology, where full mesh topology is a type of tree diagram topology each of the descendat connects to other descendent.


So, okay, now how to solve the tree diagram traversing algorithm?
It essentially, opening first door and write the next door, recursively; loop back from the beginning again.

SMALL BASIC: Removing unwanted element

Hi, SMALL BASIC programmer, welcome.

In this tutorial, we will learned about removing unwanted element from an array, in this case from a single line multi colomn (SLMC) array not multi line multi colomn (MLMC). So, watch it.

For example, we want to remove element that have value FAILED from an SLMC array.

There are couples method that you can do to this, but I prefer this. If you do this differently, you will get different experience.

x[0] = "SUCCESS"
x[1] = "FAILED"
x[2] = "SUCCESS"
x[3] = "SUCCESS"

k = 0
m = 0
For i = 0 To 3
  If x[i] = "FAILED" Then
    x_l = Array.GetItemCount(x) - 1
    'Move the front and the back
    For j = i + 1 to x_l
      y[k] = x[j]
      k = k + 1
    EndFor
    For l = i - 1 To 0
      z[m] = x[l]
      m = m + 1
    EndFor
    'Merge y and z, merge y to the back of z
    '1st. Search the length of z
    z_l = Array.GetItemCount(z) - 1
    '2nd. And then transfer one by one
    For transfer_index = 0 To z_l
      y[Array.GetItemCount(y)] = z[transfer_index]
    EndFor
  EndIf
EndFor

TextWindow.WriteLine(y)
 
   
   

SMALL BASIC: Checking elements are same value or not

Hi, Small Basic programmer, welcome.

In this tutorial we will learned about a program that check whether values of colomn of the same row of an array are same or not same using SMALL Basic.

This is useful sometimes when you program and few situations.

So here is the program:
y[0] = "Failed"
y[1] = "Success"
y[2] = "Failed"

y_l = Array.GetItemCount(y) - 1
For i = 0 To y_l
  If y[i] = "Success" Then
    TextWindow.WriteLine("Not all failed")
    Goto quitloop
  Else
    If i = y_l then
      TextWindow.WriteLine("All failed")
      EndIf
      EndIf
EndFor
  quitloop:
