Thread: need someone to check my coding

Looks like there's lots of crazy stuff going on.
1.) incr() is declared as void yet returns a zero?
2.) add() is declared as returning an INT yet really returns a complexNumber
3.) Reread about using static variables

Try this:

Code:

#include<iostream>
using namespace std;

class complexNumber
{

       private:
                float realPart;
                float imgPart;
                static int count;

       public:
       complexNumber ( float real=0,float img=0);
       
       void show();

       int getcount();
       int incr();
       friend complexNumber add(complexNumber, complexNumber);
     
};

int complexNumber::count=0;

int complexNumber::getcount()
{
    return complexNumber::count;
}

complexNumber::complexNumber(float real, float img)
{
               realPart = real; 
               imgPart = img;

               count++;
}

complexNumber add(complexNumber a, complexNumber b)
{
              complexNumber c;
              c.realPart=a.realPart+b.realPart;
              c.imgPart=a.imgPart+b.imgPart;
              return c;
}

void complexNumber :: show()
{
           cout<< realPart<< "+"<< imgPart<<"i"<<endl;
}

int complexNumber :: incr()
{
     complexNumber a;
     a.realPart++;
     return 0;
}

int main()
{

    complexNumber a(2.0, 1.0);        
    a.incr();
    a.show();

    return 0;   
}

I still don't think this is really going to do everything you think it is, your incr() for example, but this might get you going.
