#includeThis example uses the getX() function to retrieve the x-coordinate of a mouse click position in a graphics window. Package Library: The package library used in this example is "graphics.h", which is defined in the "winbgim.h" header file. This package library provides a set of functions and tools for graphics programming in C++, including window initialization, drawing shapes, keyboard and mouse input handling, etc. Example 2: Get X-coordinate of a Position object ```cpp #include#include int main() { int x, y; initwindow(800, 600); // initialize a graphics window while (!ismouseclick(WM_LBUTTONDOWN)) {} // wait for a mouse click getmouseclick(WM_LBUTTONDOWN, x, y); // get the mouse click coordinates std::cout << "X-coordinate: " << getX(x) << std::endl; closegraph(); return 0; }
