Question

What does it mean to call a class like this:

class Example {  public:    Example(void);   ~Example(void); }  int main(void) {  Example ex(); // <<<<<< what is it called to call it like this?   return(0); } 

Like it appears that it isn’t calling the default constructor in that case. Can someone give a reason why that would be bad?

Thanks for all answers.

Answer 1

Currently you are trying to call the default constructor like so.

Example ex(); 

This is not actually calling the default constructor. Instead you are defining a function prototype with return type Example and taking no parameters. In order to call the default constructor, omit the ()’s

Example ex;
