Question

I have been working on a class and it is all big and ugly and would like to split each bit into its own cpp/.h files.

I can not seam to work out how to do this…

Here is my code

I understand that you place the class in the .h and the implementation in the .cpp… but I just can not get it to run, where it runs fine in a single file.

Make sure you don’t forget to put:

#include "HeaderFile.h"

in the cpp file, where “HeaderFile.h” is the name of the “.h” file containing the definition of the class you want to use in the cpp file.

If you have a file “MapFrames.h” containing:

#include <iostream>
#include <vector>
#include <algorithm>
#include <stdio.h>
#include <math.h>
using namespace std;

class MapFrames{
public:
    char frame[11];
    vector<short> cols;
    vector<short> rows;
    MapFrames (short a, short b);
};

then the cpp file “MapFrames.cpp” should contain:

#include "MapFrames.h"

MapFrames::MapFrames (short a, short b){
    // Construct a vector "rows" of a certain user defined size
    rows.resize(a);
    // Construct a vector "cols" of a certain user defined size
    cols.resize(b);
    //Construct Frames
    frame[0]=201; // Top LC
    frame[1]=205; // Horizontal
    frame[2]=187; // Top RC
    frame[3]=186; // Vertical
    frame[4]=200; // Bottom LC
    frame[5]=188; // Bottom RC

    //Construct Icons
    frame[6]=219;  // ICON: Hidden Locations 
    frame[7]=177;  // ICON: Spy Location: Nothing Found
    frame[8]=2;    // ICON: Spy Location: City Found
    frame[9]=127;  // ICON: Miss
    frame[10]=15;  // ICON: Destroyed City
}
