#include <iostream>

int main()
{

    Point piste1;
    piste1.setXY(1,3);
    
    Point piste2(12, 23);
    
    Point piste3(piste2);
    
    system("PAUSE");
    return 0;
}

I see a typo here:

Point::Point(int xx, int yy)
{
    x=xx;
    y=yx;                         
}

Apart from that, what specifically do need help with?

What problems?

When I try compiling the code, I get a lot of linker errors.

[Linker error] undefined reference to `Point::Point()'
[Linker error] undefined reference to `Point::setXY(int, int)'
[Linker error] undefined reference to `Point::Point(int, int)'
[Linker error] undefined reference to `Point::Point(int, int)'
[Linker error] undefined reference to `Point::~Point()'
[Linker error] undefined reference to `Point::~Point()'

etc.

Well, probably your source file "point.cpp" is not in your workspace. Check and try again.

The compilation must first generate object file from each *.cpp file and then the linker has to access both object files (and necessary libraries) to produce the executable.

You have code for the methods, so the build rules probably do not include the Point.cpp (and/or corresponding object file). The fix depends on your build environment.
