Here's the code: (It's got more things than it needs for what it does, but that's because its part of a bigger scheme.

#include <iostream> using namespace std; // Var Space // End Var Space // Class Space // Class Dec/Def Space class Object { public: Object(); ~Object(); // Location Mods int ChangeX(int degree); int ChangeY(int degree); // End Location Mods // Time Mods int ChangeYear(int degree); int ChangeMonth(int degree); int ChangeDay(int degree); int ChangeMinute(int degree); int ChangeSecond(int degree); // End Time Mods // Output int ReadX(); int ReadY(); int ReadYear(); int ReadMonth(); int ReadDay(); int ReadMinute(); int ReadSecond(); // End Output protected: // Location Var int X; int Y; // End Location Var // Time Var int Year; int Month; int Day; int Minute; int Second; // End Time Var }; // Class Func Space // Object Class Func Space Object::Object() { int X = 0; } Object::~Object() { // Hello } int Object::ChangeX(int Degree) { X = X + Degree; }; int Object::ChangeY(int Degree) { Y = Y + Degree; }; int Object::ChangeYear(int Degree) { Year = Year + Degree; }; int Object::ChangeMonth(int Degree) { Month = Month + Degree; }; int Object::ChangeDay(int Degree) { Day = Day + Degree; }; int Object::ChangeMinute(int Degree) { Minute = Minute + Degree; }; int Object::ChangeSecond(int Degree) { Second = Second + Degree; }; int Object::ReadX() { cout << X; }; int Object::ReadY() { cout << Y; }; int Object::ReadYear() { cout << Year; }; int Object::ReadMonth() { cout << Month; }; int Object::ReadDay() { cout << Day; }; int Object::ReadMinute() { cout << Minute; }; int Object::ReadSecond() { cout << Second; }; int main() { Object Ball; Ball.ReadX(); cout << endl; Ball.ChangeX(5); cout << "Incremented by 5 \n"; Ball.ReadX(); cin.get(); return 0; };

Oh yeah, and its in Dev C++ incase its not portable.

Try using 'main' instead of 'Main'.

That may still not work since it's looking for a WinMain. Something in your linker is telling it to create a Windows application, so it wants to see a WinMain function. I think you may just want to create a console application. Look at your linker options and figure out how to just create a console application.

Maybe try using WinMain instead of main and see what happens. But I really don't think this is what you want in your case. Also, WinMain has a different signature than WinMain.

This one is extremely unlikely, but you don't happen to have a .DEF file with WinMain defined, do you?

Its not exactly local. Its a protected object specific. its initialized here:

EDIT: when you have instance variables, ALWAYS initialize them to '0', especially if they're pointers. I prefer to do it this way:

Object::Object() : X(0), Y(0){
//...
}

All i can say is that the following code works fine for me. Output :
0
increment by 5
5

#include <iostream> using namespace std; // Var Space // End Var Space // Class Space // Class Dec/Def Space class Object { public: Object(); ~Object(); // Location Mods int ChangeX(int degree); int ChangeY(int degree); // End Location Mods // Time Mods int ChangeYear(int degree); int ChangeMonth(int degree); int ChangeDay(int degree); int ChangeMinute(int degree); int ChangeSecond(int degree); // End Time Mods // Output int ReadX(); int ReadY(); int ReadYear(); int ReadMonth(); int ReadDay(); int ReadMinute(); int ReadSecond(); // End Output protected: // Location Var int X; int Y; // End Location Var // Time Var int Year; int Month; int Day; int Minute; int Second; // End Time Var }; // Class Func Space // Object Class Func Space Object::Object() { X = 0; } Object::~Object() { // Hello } int Object::ChangeX(int Degree) { X = X + Degree; }; int Object::ChangeY(int Degree) { Y = Y + Degree; }; int Object::ChangeYear(int Degree) { Year = Year + Degree; }; int Object::ChangeMonth(int Degree) { Month = Month + Degree; }; int Object::ChangeDay(int Degree) { Day = Day + Degree; }; int Object::ChangeMinute(int Degree) { Minute = Minute + Degree; }; int Object::ChangeSecond(int Degree) { Second = Second + Degree; }; int Object::ReadX() { cout << X; }; int Object::ReadY() { cout << Y; }; int Object::ReadYear() { cout << Year; }; int Object::ReadMonth() { cout << Month; }; int Object::ReadDay() { cout << Day; }; int Object::ReadMinute() { cout << Minute; }; int Object::ReadSecond() { cout << Second; }; int main() { Object Ball; Ball.ReadX(); cout << endl; Ball.ChangeX(5); cout << "Incremented by 5 \n"; Ball.ReadX(); cin.get(); return 0; };

possibly if it IS an IDE issue, then try creating a new project (make sure it's a console project, not a win32 one)

I would seriously consider using C# as an alternative. C# is a real alternative to C++ and in my opinion even surpasses it. If you're up for some reading you can find a list of links on the C++ vs C# subject in this GameDev theread:

I might be outnumbered by 3:1 on this issue but C# will spare you a lot of headache ( no linkage problems, he header files, simplified syntax, to name just a few). You really don't care about the 5% penalty many like to talk about. Beside that I really don't see any major advantage from using C++ (maybe except the case were you want to get a job in the gamedev industry in the next few months which I don't think is your case)

P.S. with multicore processors flooding the market, processing speed is no longer the bottleneck in software development (more so in gamedev).
