Yes, absolutely. That would work like

class MyClass {
public:
    void foo(int x = 42) {
        std::cout << "this is 'foo()' called with " << x << std::endl;
    }
};                         

Open in new window


or

//MyClass.h
class MyClass {
public:
    void foo(int x = 42);
};

Open in new window

// MyClass.cpp
#include <iostream>
#include "MyClass.h"
    void MyClass::foo(int x) {
        std::cout << "this is 'foo()' called with " << x << std::endl;
    }

Open in new window


The default values have to be given with the declaration, not the implementation.
