Code Relax #3 [ by rox_rook ]

- Write a class that allows operator overloading as long as possible and no syntax error.
Example, the following expression must be evaluated:

+++++++++++++++++++++++++++++++x; // must be valid and evaluated

- Language in use: C++

Solution [ by me ]

#include <iostream>

using namespace std;

template< typename X >
class MyOperator {
    private:
        X value;
    public:
        MyOperator( X _value = 0 ) : value(_value) { };
       
        MyOperator& operator+() {
            ++value;
        }
        MyOperator& operator++() {
            ++value;
        }

        X getValue() const { return value; }
};

int main( )
{
    MyOperator<int> x(7);
    ++++++++++++++++++++++++++++++++++x;
    cout << x.getValue() << endl;
   
    MyOperator<double> j(1.4);
    +++++++++++++++j;
    cout << j.getValue() << endl;

    return 0;
}

Evaluation
- The keyword 'operator' in C++ can be use to make cool things. I just found out about this 'til today testing it.
