Factorial using while loop in C Programming

Code goes like this :

/* Factorial calculation using While loop */
#include<stdio.h>
#include<conio.h>
int main()
{
    int i,num,fact=1;
    i=1; //counter initialization
    printf("Enter any number: ");
    scanf("%d",&num);   
    while(i<=num)
    {
        fact*=i;    //Factorial calculation
        i++;         //Counter Increment
    }
    printf("\n The factorial of %d is %d",num,fact);
    return 0;   
}

Output :

I have used Dev CPP to compile this program.
If you are using Turbo C++ IDE, then use conio.h in link section after stdio.h
and use getch(); to hold the output screen, just before the end of main function.
If you have any confusion regarding the program, please, comment below.
Happy Coding !
Thank you
