Program

//C program to find Factorial of a Number Using Function

#include<stdio.h>
int factorial(int num)
{  int i = 1, fact = 1;
   do
  {
      fact=fact*i;
      i++;
  } while(i<=num);

  return (fact);
}

void main()
{
  int n;

  printf("Enter a number: ");
  scanf("%d",&n);

  printf("Factorial of %d is: %d",n,factorial(n));

}

Output

Enter a number: 7
Factorial of 7 is: 5040
