I have used Code::blocks 12 compiler for debugging purpose. But you can use any C programming language compiler as per your availability.

#include <stdio.h>
 
// Function declaration
unsigned long long Findfact(int num);
 
 
int main()
{
    int num;
    unsigned long long factorial;
 
    // Inputting an integer from user
    printf("Enter any number: ");
    scanf("%d", &num);
 
    factorial = Findfact(num);
 
    printf("Factorial of %d is %llu", num, factorial);
 
    return 0;
}
 
unsigned long long Findfact(int num)
{
    // Base condition
    if(num == 0)
        return 1;
    else
        return num * Findfact(num - 1);
}

Result:

Enter any number: 5

Factorial of 5 is 120
