Default constructor

[Lio]

Why,after I initialize an object the print function is giving me error
Thanks

#include <iostream>
using namespace std;
class A
{
public:
    A()
        :varI(0),varD(0)
    {
    }
    void print()
    {
        cout<<"int:"<<varI<<" double:"<<varD<<endl;
    }
private:
    int varI;
    double varD;
};
int main()
{
    A o1();
    o1.print();
}

[Moschops]

A o1();

This is declaring the existence of a function named o1 that takes no parameters and returns an object of type A.

[vlad from moscow]

Because your definition

A o1();

the compiler considers as a definition of a function that has return type A and has no parameters.

To correct your definition you should write

A o1;
