problems with parameritized class constructors

[enduser000]

Why dosen't this work? Thanks again for taking a look, as far as I know the syntax is correct.

//parameterized constructors
#include <iostream>
using namespace std;

class MyClass{
public:
	int x;

	MyClass();
	~MyClass();
};

// parameterized constructor
MyClass::MyClass(int i){
	x = i;
}

//destructor
MyClass::~MyClass(){
	cout << "x was " << x << " removing whole object...\n";
}
int main(){
	MyClass ob1(101);

	MyClass ob3(301);

	MyClass ob2(200);

	cout << "ob1.x: " << ob1.x << "\nob2.x: " << ob2.x << "\nob3.x: " << ob3.x;

	return 0;
}

Errors:
classparam.cpp
classparam.cpp(14) : error C2511: 'MyClass::MyClass(int)' : overloaded member function not found in 'MyClass'
classparam.cpp(5) : see declaration of 'MyClass'
classparam.cpp(23) : error C2664: 'MyClass::MyClass(const MyClass &)' : cannot convert parameter 1 from 'int' to 'const MyClass &'
Reason: cannot convert from 'int' to 'const MyClass'
No constructor could take the source type, or constructor overload resolution was ambiguous
classparam.cpp(25) : error C2664: 'MyClass::MyClass(const MyClass &)' : cannot convert parameter 1 from 'int' to 'const MyClass &'

Once again, thanks for looking.

You must declare the constructor as part of the class before you can define it.

class MyClass {
  public:
    int x;
    MyClass();       // declaration, not definition
    MyClass(int i);  // again, it must be declared
    ...
  };

MyClass::MyClass(): x(0) { }  // definition of default constructor

MyClass::MyClass(int i): x(i) { }  // definition of the only parameterized ctor

...

Hope this helps.

Thanks, forgot it in the prototype like you said.

Revised code:

//parameterized constructors
#include <iostream>
using namespace std;

class MyClass{
public:
	int x;

	MyClass(int i);
	~MyClass();
};

// parameterized constructor
MyClass::MyClass(int i){
	x = i;
}

//destructor
MyClass::~MyClass(){
	cout << "x was " << x << " removing whole object...\n";
}
int main(){

	MyClass ob1(5);
	MyClass ob2(19);

	cout << "ob1.x: " << ob1.x << "\nob2.x: " << ob2.x << '\n';

	return 0;
}
