What is the basis for determining function overloading in C++?

The determination of function overloading in C++ is based on the function’s parameter list. When the function name is the same but the parameter list is different (including parameter types, quantities, or order), function overloading occurs. The compiler determines which overloaded function to call based on the differences in the parameter list. The return type of the function and the function name itself do not affect the determination of function overloading.
