write a program to find factorial of a number using both methods

 // C program to find factorial of given number

#include <stdio.h

// function to find factorial of given number

unsigned int factorial(unsigned int n)

{

if (n == 0)

return 1;

return n * factorial(n - 1);

}

int main()

{

int num = 5;

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

return 0;

}

 

or or .........................................

#include <stdio.h>

// function to find factorial of given number

unsigned int factorial(unsigned int n)

{

int res = 1, i;

for (i = 2; i <= n; i++)

res *= i;

return res;

}

int main()

{

int num = 5;

printf(

"Factorial of %d is %d", num, factorial(num));

return 0;

}
