Function Overloading in C++ You can have multiple definitions for the same function name in the same scope. The definition of the function must differ

Whenever you declare more than one function with the same name in the same scope, you are overloading the function name. The function can be an ordinary function, member function, constructor, or overloaded operator. Overloaded functions must differ in their parameter lists: they must have a ...

pass >>> t = Test() >>> To avoid name mangling in Pascal, use: exports myFunc name 'myFunc', myProc name 'myProc'; Free Pascal supports function and operator overloading, thus it also uses name mangling to support these features. 遇到需要名字修饰的时候,Python把这些名字改成单下划线加...
So if our user-defined conversion had been to type char instead of int, the compiler would have used the user-defined conversion to char and then promoted the result into an int to match. Related content We discuss how to create user-defined conversions for class types (by overloading the...
