Introduction to Microservice Architecture Using SpringBoot - Part 1

Write a C Program To calculate factorial of an integer number. (try taking big number also). 

 

 #include <stdio.h>   
 unsigned long long int factorial(unsigned long long int n)   
 {   
      if (n == 0)   
           return 1;   
      return n * factorial(n - 1);   
 }   
 int main()   
 {   
      unsigned long long int fact,num;  
      printf("ENTER A NUMBER : ");  
      scanf("%lu",&num) ;  
      fact=factorial(num);  
      printf("Factorial of %lu is %lu", num, fact);   
      return 0;   
 }   

OUTPUT :
