Why is that? thank you

#include <stdio.h> 
class res 
{ 
   int a[6],i; 
   public: 
   int result() 
   {
      for(i=0;i<3;i++) 
      { 
         if(a[i]%3==0)

First you need to understand that the array variable in main is different from the class member a. And in result method, class variable a is not initialized with valid values to do a % operation on it.

if(a[i]%3==0) 
{
    "sum=sum+a[i]"; // And probably here you meant sum=sum+a[i];
                    // string should be enclosed in double quotes.
}

With the above modification made, class res doesn't know what the variable sum is.

Given the number of many other mistakes in your program, I suggest you to read a book from the suggested link.
