redefine error (multiple files)

ah never mind I'm getting ahead of myself. I never implemented the destructor. Sorry for the waist of a post. I guess there should be a rule like think about a problem for at least 24 hours before posting

When I compile I get this error, even though I assign the variables a value only once in a single file.

>C:\MinGW\bin\g++ -pedantic -Os main.cpp -o main.exe

//I am uneasy about these being in the global scope of the interface file

};

    {
        onBranch = (int *) realloc(onBranch, (dielemas+1)*sizeof(int));
        onBranch[dielemas++] = currentTime;
    }
}

int Branch::randNumber()

    int random_integer;
    int range=(LOWEST-HEIGHEST)+1;
    return random_integer = LOWEST+int(range*rand()/(RAND_MAX + 1.0));
}

Code:

#ifndef BRANCH_INCLUDED

#endif

const int TREE_HEIGHET = 20;

Code:

#include <iostream>
#ifndef BRANCH_INCLUDED
#define BRANCH_INCLUDED
#include "Branch.h"
#endif

using namespace std;

Tree::Tree()
{
    Branch dielema;//dielema is the variable with the caged birds
    for(int i = 0; i<TREE_HEIGHET; i++)
    {
        
        dielema = Branch();
        treeBranch[i] = dielema;
    }
    
    
}

The lines in bold I added later. Now whenever I try to compile I get >C:\MinGW\bin\g++ -pedantic -Os main.cpp -o main.exe

Just as an FYI, I'd rethink how you set up your header and source files. You aren't following standard practice with your header include guards, and you also should not normally #include cpp files. I'd suggest doing some more research on header include guards and setting up projects with multiple files. If you have questions feel free to post them here (make sure to mention which IDE or compiler you use).
