Program compiles; won't build
Using MSVC++ 6.0; this program compiles but will not build. Is it simply a compiler error, or is there something wrong with the code?
If someone could post a snippet of the results, I'd appreciate it.
Code:
#include <iostream>
#include <iomanip>

void setX( int ); // set x in coordinate pair
int getX() const; // return x from coordinate pair; getX is not a member of cylinder
void setY( int ); // set y in coordinate pair
int getY() const; // return y from coordinate pair
void print() const; // output Point3 object
private:
int x; // x part of coordinate pair
int y; // y part of coordinate pair
}; // end class Point3
