C Program to Calculate Factorial of a Number

Factorial of an integer is the product of the integer and all the integers below it; e.g. factorial five ( 5! ) is equal to (5*4*3*2*1) =120.

//C Program to calculate factorial of a number

#include<stdio.h>

int main()
{
    int n, i, fact=1;
    printf("Enter a number: ");
    scanf("%d", &n);
    
    for (i=1; i<=n; i++)
    {
        fact=fact*i;
    }
    
    printf("Factorial = %d", fact);
    return 0;
}
