Mouse and Cat Game In C++
1 like•868 views
This document describes a mouse and cat game programmed in C++. It includes class definitions and methods for game objects like the mouse and cat that control their positions randomly on the game grid. Methods are provided to run the game, check for collisions between objects, and save/load the game state to files.
