C Program to find factorial of a number using the function


In this program, You will learn how to find factorial of a number using a function in c


3! = 1 * 2 * 3

4! = 1 * 2 * 3 * 4

Example: How to find factorial of a number using a function in c

#include<stdio.h>

int fact(int n) {
   int f = 1, i;
   for (i = 1; i <= n; i++) {
       f = f * i;
   }
   return f;
}

int main() {
   int n, fa;
   printf("Enter a number:");
   scanf("%d", &n);

   fa = fact(n);
   printf("Factorial is:%d", fa);

   return 0;
}

Output:

Enter a number:4                                                                                                                       
Factorial is:24
