Operator Overloading

[Vikram Narayan]

What is wrong with my code snippet?

#include <iostream>
#include <ostream>
#include <iomanip>

using namespace std;

class X
{
    int Number;
    public:
    void operator+();
    X(int);
};

void operator+(X,X);
void operator+(X,double);

int main()
{
    X a;
    cout << a+1<< setw(5) << 1+a<< endl;
    return 0;
}

This is the error which is returned.
error: no matching function for call to ‘X::X()’

You did not declare a constructor for class X all you did was call a prototype.
