String problems

[DisobeyedCoot]

Well I have made this program with a class that when called with the setMessage() it will set the message then when getMessage() is called it should display the message but I just get compiler errors.

Code for Main.cpp:

#include "Message.h"
#include <iostream>
#include <string>


using namespace std;

int main()
{
	Message msg();
	msg.setMessage();
	msg.getMessage();
	return 0;
}

code for Message.h

#include <iostream>
#include <string.h>


class Message
{
public:
	Message(std::string initialMessage);
	~Message();
	std::string getMessage() { return message; }
	void setMessage(std::string message);
private:
	std::string message;
}

Message::Message(std::string initialMessage)
{
	setMessage(initialMessage);
}
Message::~Message() {}

void Message::setMessage(std::string newMessage)
{
	std::cout << "Please enter a message:\n";
	std::cin >> newMessage;
	message = newMessage;
}

You don't seem to understand function parameters, so you should look that up again.

Explain. Please

[Athar]

setMessage takes one parameter, but you're not passing any arguments when calling the function in main(). The same applies to the Message constructor.

Message msg(); parses as a function declaration, by the way.
Write Message msg; instead (if your class had a default constructor).

void Message::setMessage(std::string newMessage)

This means when you call this function, it is expecting a string to be passed. An example would be,

messageObj.setMessage(myString);
