Problem 1. Unlike C, the C++ language allows procedure (method) names to be "overloaded. That is, multiple methods can have the same name, as long as they have different type signatures, i.e., they take different types or numbers of parameters. What is the name of the technique used by the compiler to enable the linker to do its work in this case? Explain exactly what the compiler does to allow the linker to distinguish between two C++ methods declared in the same class aClass, where one is declared void foo(int x, int y), and the other void foo(long z)
