I know that default constructors initialize objects to their default values, but how do we view these values? If there's a variable of type int, it is supposed to be initialized to 0. But how do we actually view these default values of the constructors? Can anyone please provide a code snippet to demonstrate the same?
Good coding practice: write your own constructor, so you know how it will be initialized. This is portable and guaranteed to always have the same behaviour. Your code will be easier to read and the compiler knows how to make that efficient, especially when using the special notation:
class Foo
{
public:
Foo() : i(0), j(0) {}
private:
int i;
int j;
};
