C++ is same type
WebThe only difference between both prototypes is the use of either the keyword class or the keyword typename.

These functions having the same name but different arguments are known as overloaded functions. For example: // same name different arguments int test() { } int test(int a) { } float test(double a) { } int test(int a, double b) { }
