Factorial of a integer number in C

Factorial of n is the product of all positive descending integers. Factorial of n is denoted by n!. For example:

5! = 5*4*3*2*1 = 120  

3! = 3*2*1 = 6  

Here, 5! is pronounced as "5 factorial", it is also called "5 bang" or "5 shriek".

The factorial is normally used in Combinations and Permutations (mathematics). 

/* To find factorial of a integer */
#include<math.h>
#include<stdio.h>
int main()
{
    int n, i, fact=1;
    printf("Enter the No.:");
    scanf("%d", &n);
    for (i=1;i<=n;i++)
    fact=fact*i;
    printf("\n The factorial of %d is : %d\n", n,fact);
    return(0);
}
