Exit Codes

Exit codes are numerical values returned by a program to the operating system upon completion, signaling whether the execution was successful or encountered errors. A return value of 0 typically indicates success, while non-zero values denote failure, with the specific meaning of each non-zero code being application-dependent. In C++, you can specify the exit code using the return statement within the main function or by calling the exit() function from the <cstdlib> header.
