Question

I am trying to compile this code, and g++ keeps telling me that ‘TimeFinder’ has not been declared

Header File

#ifndef _TIMEFINDER_H
#define _TIMEFINDER_H
#include <vector>
#include "timefinder.cpp"
using namespace std;
class TimeFinder
{
public:
    static vector<int> time_from_name(string filename);
    static int calc_seconds (vector <int> time);

};
#endif

CPP File

#include "timefinder.h"
using namespace std;
vector<int> TimeFinder::time_from_name(string filename)//Line 14
{
    //Method Body
}

int TimeFinder::calc_seconds (vector <int> time1)//Line 37
{

    //Method Body
}

Why is this going on? I looked at other examples online, and my code seems to match what works for other people…

Edit: The exact error messages are

timefinder.cpp:14: error: ‘TimeFinder’ has not been declared

timefinder.cpp:37: error: ‘TimeFinder’ has not been declared

Edit2: I’m sorry I’m not very good at this yet, but I would like to thank everyone for their suggestions. Hopefully my code quality will begin to improve because of them.

Do not do this:

#include "timefinder.cpp"

You are pulling your definitions into your header so they appear before their declarations.

There is a lot of other stuff wrong with your code – the use of static members in the first place, passing vectors and strings by value when they should be references, and placing using directives in header files, but removing that #include should fix the immediate problem.
