Constructing Objects and Calling Member functions

Question

Here is my code

#include 

using namespace std;

class MyTestClass
{
    int MyTestIVar;

    public: 
        MyTestClass(void);
        int         


        

Answer 1

You have stumbled upon the most vexing parse.

The line

MyTestClass mTC();

is parsed as a function prototype of a function named mTC which has no arguments and returns an instance of MyTestClass.
