Why does an error occur when running the game code in C++?

There can be various reasons why an error occurs when running game code in C++. Some common reasons for errors include syntax errors, logic errors, memory issues (like accessing out-of-bounds memory), uninitialized variables, incorrect data types, missing files or libraries, and platform-specific issues. To help identify and resolve the specific error, it would be helpful to review the code, check for any error messages or warnings provided by the compiler, and troubleshoot any potential issues step by step.
