C program for factorial of a number with recursion

#include<stdio.h>
int factorial(int num){
  if(num==1){  //Termination condition for recursion
    return 1;
  }
  else{ 
    return num*factorial(num-1);  //Recursive call to evaluate recursively factorial of n-1
  }
}
int main(){
  int number,result;
  printf("Enter the number to find factorial\n");
  scanf("%d",&number);  //user input for number
  result=factorial(number);  //call to factorial
  printf("Factorial of %d is %d\n",number,result);
  return 0;
}
