How To Create a Loading Screen in C++

Let us Learn how to create a loading Screen in C++.

Firstly I would like to tell you that it works on simple and logical loops.

Also the outputs like : 

• Creating Temporary files
• Accessing Main Memory
• Accessing Cache

are also based on the counter in these loops.

So here is the Source Code:

#include<iostream.h>

#include<conio.h>

#include<dos.h>

 void main()

 {

   clrscr();

     for(int i=1;i<=50;i++)

      { clrscr();

 cout<<"\n\n\n\n\t\t\t\t   Loading "<<'\n'<<'\t'<<'\t';

for(int j=1;j<=i;j++)

 cout<<"²";

 cout<<"\n\n\t "<<2*i<<"%";

if( i > 1 && i < 20)

 cout<<"\n\n\tCreating Temporary files";

else if( i > 20 && i<40)

 cout<<"\n\n\tAccessing Main Memory";

else if(i >40 && i<48)

 cout<<"\n\n\tAccessing Cache";

else cout<<"\n\n\tComplete. Press Enter to Continue ";

 delay(150 - i*3);

      }

 getch();

 }

So basically there are 2 loops, the outer and the inner.
The outer loop starts from 1 goes till 50. the reason for taking the end point as 50 is that in the inner loop the counter has been used to determine the % loaded and the variable is multiplied by 2.
The delay function is used so as to make the loading screen look realistic by making it faster as the loading % increases. The formula derived in it is based on the output statement being used ie cout<<"ASCII 219";. You can do it by pressing and holding the left Ctrl key an typing 219 and leaving the key.
