C Program to Find Factorial
- There are three methods to find and print factorial of a number.
- Three methods are, the first one uses for loop, the second uses a function to find factorial and the third uses recursion.
- A factorial is product of all the numbers from 1 to n.
- Factorial is represented using '!'.
Sample Code
#include<stdio.h>
int main()
{
int i,f=1,n=6;
printf("Natural number:6 ");
for(i=1; i<=n; i++)
f = f * i;
printf("\n%d!=%d\n", n, f);
return 0;
}
Output
Natural number:6
6! = 720
