Question

I’m using Xcode for C++ on my computer while using Visual Studio at school.
The following code worked just fine in Visual Studio, but I’m having this problem when using Xcode.

clock c1(2, 3, 30);

Everything works just fine, but it keeps giving me this error that says “Expected ‘;’ before ‘c1′”

Fine, I put the ‘;’ .. but then, it gives me this error: “‘c1’ was not declared in this scope”

Here’s the whole header code:

#include <iostream>
using namespace std;

class clock
{
private:
 int h;
 int m;
 int s;

public: 
 clock(int hr, int mn, int sec);
};

clock::clock(int hr, int mn, int sec)
{
 h = hr;
 m = mn; 
 s = sec;
}

Here’s the whole .cpp code:

#include "clock.h"

int main()
{
    clock c1(2, 3, 30);
    return 0;
}

I stripped everything down to where I had the problem. Everything else, as far as I know, is irrelevant since the problem remains the same with just the mentioned above.

Thanks in advance!

Answer 1

There is a function clock that will hide your clock class of the same name. You can work this around by saying

class clock c1(2, 3, 30);

It’s very bad practice to do using namespace std; in a header. Instead put that line into the cpp file only. It may solve your problem if you remove that line (if the name comes from namespace std:: instead of from the global namespace originally).
