Why Doesn't My Class Constructor Get Called?

Why is there no call to the constructor?

The provided code seeks to create an instance of the Class class; however, its current implementation results in unexpected behavior. The code defines a constructor, which should be executed upon object creation, but the output does not reflect this.

Upon closer examination, the code contains a crucial error. The line Class object(); is not correctly declaring an object of the Class class. Instead, it is mistakenly declaring a function with the same name as the class.

To rectify this issue, the code should be modified to correctly create an instance of the Class class:

#include<iostream>
using namespace std;

class Class
{
public:
    Class()
    {
        cout << "default constructor called" << endl;
    }

    ~Class()
    {
        cout << "destructor called" << endl;
    }
};

int main()
{
    Class object; // Corrected line: Create an object of Class
}

With this correction, the expected output will be produced, as the default constructor is now properly called upon object creation.
