I think that the problem is here:

C++

void main();

The semicolon in C tells to the compiler that a statement[^] is complete.
In this case we are defining the function 'main' which is a declaration Compound statement[^].
Closing such a declaration before the body is an error. The correct code is:

C++

void main()
{
   ...    //Function body code
}

For sake of completeness I would add that closing before body some other compound statement, where the body is not mandatory, is not an error.
I.e. a while, a for, etc.

C++

for (i=0; i<10; i++)
  ;    //Do nothing

This coulld be write also as:

C++

for (i=0; i&lt;10; i++);    //Equivalent to former

Solution 1

It could be

C++

printf("Sum of values: %d", d);

Please see:
