Undefined reference means that the linker is not able to find a symbol definition in any object file, but it’s still referenced. Undefined reference error is not C++ language-specific but rather a result of the executable program generation process. The latter process roughly works as follows: the compiler translates the human-readable source code into machine instructions and generates objects files.
