Classes cannot return values, only functions can return values. But you cannot return a function from a function, you can only return a function pointer -- a pointer variable holding the address of the function you wish to return. All possible return values must be of the same type, therefore all function signatures and return types must be exactly the same -- only the name of the functions can differ.

#include<iostream> class foo{ int m_data; }; int main() { foo* p=new foo; delete( foo), foo=NULL; return(0); }
template<class T> T& max(const T& x, const T&y){return(x>y?x:y); }
It depends on what you mean by 'types class'. Here is the shortest C program, without any 'types class': int main (void) { return 0; }
Constructors have the same name as the class itself and they do not specify a return type, not even void because they return the instance of the class itself. Because constructors have the same name as the class then they allow method overloading and also save memory and execution time of program. Program release memory of constructors function after using this function and it reduce program complexity.
Use the following template function: template<class T> T& max(T& x, T& y){return(y<x?x:y;}
public class AddNumbers{ public int add(int a, int b){ return a + b; } }

You don't write programs in a class in C++, you write programs that use classes. Every C++ has at least one function, main, the entry point of the application. You define the classes and functions that are used by your main function. Classes allow you to classify the objects used by your program, allowing data to be manipulated in a highly controlled manner, ensuring consistency and robustness throughout your program.

True - A C++ constructor cannot return a value.

Yes you can use the same function name for a member function and an external function. They are primarily distinguished by the number and type of arguments they accept (the function signature). If they match exactly, then the scope resolution operator (::) is used to differentiate them by namespace. The class namespace is the class name itself. The external function uses global scope unless scoped to another namespace. When the scope is not explicitly stated, then the scope is implied by the call site. Note that whenever there is any ambiguity about which function is implied, the compiler will emit an error indicating where the ambiguity lies, and the program will ultimately fail to compile.
