Answer 1

The problem is probably with your lines above line 8.

Could you please share all your code?

The full code is:-

#include <iostream>

using namespace std;

int val = 10;
divide (int)

int main()
{
    int val = 5;
    val = divide(::val/val);
    cout << ::val<<val;
}

int divide(int v)
{
 return v / 2;    
}

Replace line 6 with this:

int divide (int);

The point is, that when you declare your function, you need to match the signature of your definition and finish with a semicolon.

E.g.: [type] [name]([arguments]);

Furthermore, you'd want to put some space between the numbers you print, like this:

std::cout << ::val << ", " << val << std::endl;
