C Program To Find Factorial Of a Number Using For Loop

In this tutorial, we are going to see how to write a C program to find the factorial of a number using for loop. The factorial of a number is the product of all integers between 1 and itself. There are four ways to find a factorial of a given number, by using for loop, while loop, recursion, or by creating a function on a range from 1 to X(user entered number). Remember that the end value must be the number entered by the user + 1.
 

 

C Program To Find Factorial Of a Number Using For Loop

int main()
{
  int nbr, i, f = 1;
 
  printf("Enter a number to calculate its factorial: ");
  scanf("%d", &nbr);
 
  for (i = 1; i <= nbr; i++)
    f = f * i;
 
  printf("%d! = %ld\n", nbr, f);
 
  return 0;
}

Output:

Enter a number to calculate its factorial: 3
3! = 6
