Introduction to Microservice Architecture Using SpringBoot - Part 1

 C program to print all even numbers from 1 to n and also display their sum.

 #include<stdio.h>  
   
 int evennum(int n)  
 {  
      int sum =0, i;  
      for(i=0;i<=n;i++)  
           if(i%2==0)  
                {  
                     printf("\n%d ",i);  
                     sum=sum+i;  
                }  
      return sum;  
 }  
   
 int main ()  
 {  
      int n,sum;  
        
      printf("enter the range = ");  
      scanf("%d",&n);  
        
      sum=evennum(n);  
      printf("\nsum of %d even number = %d",n,sum);  
        
      return 0;  
 }
