Hi, i'm trying to solve the A+B problem, and it works on my computer. But the compiler of this site doesn't accept my solution. It says "Compilation error" :

"11e2cd04-2636-421c-9639-3a45ac221379
11e2cd04-2636-421c-9639-3a45ac221379(4) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int"

here is my program:

#include <iostream>
using namespace std;

main () {
     long a,b;
     cin >> a;
     cin >> b;
     cout << a+b;
 };
 Where did I do mistakes?
Thank you for attention.

try this:

#include <iostream>
using namespace std;

int main () {
     long a,b;
     cin >> a;
     cin >> b;
     cout << a+b;
 }

But, it's the same. (:

I think the difference is in return type of main.
Kindly correct if i am wrong.

Thank you so much! Finally it worked!

#include<stdio.h>

 void main()
{
    float a,b,s=0.0;
    scanf("%f%f",&a,&b);
    s=a+b;
    printf("sum=%f",s) ;
}
i don't know where is problem in this programme

no "return"

This is an example problem. You should read an FAQ to get start.

First of all you haven't shown the type of main function :)

output must be as this :
cout <<(a+b);
or:
cout <<'a+b';


sorry for my English)
