hey ive just started learning C++. i would like to to create a class that holds a char string (for name), and just a couple of other integers.
i cant seem to get the char string right. i would like it so that i could write say
myClass.SetName() sort of thing but i have no idea how i should set up the string to start with and what parameters i need to pass etc.
what i would really appreciate is if someone could spend a couple of minutes writing some code for a class that has 3 vars, name, age and height say. and then show how to use the class. I think learning by example is the best way so here i am hoping to find someone who can help me.

Well thanks very much

Danny.

Example

#include <iostream>
#include <string>

using namespace std;

Class MyClass
{
public:	
	MyClass();	// Constructor
	~MyClass();	//Destructor
	void SetName();
	void PrintAll();
	void SetAge();
	void SetHeight;
private:	
	
	string name;
	int age;
	string height;
};

MyClass::Student()
{
name = "";
age = 0;
height = 0;

}

MyClass::~Student()
{
// Destructor
}

void MyClass::SetName()
{
cout << " Enter your first name: " << endl;
cin >> name;
cout << endl;
}

void MyClass::SetAge()
{
cout << " Enter your Age: " << endl;
cin >> age;
cout << endl;
}

void MyClass::SetHeight()
{
cout << " Enter your Height: " << endl;
cin >> height;
cout << endl;
}

void MyClass::PrintAll()
{
cout << " Name: " << name << endl;
cout << " Age: " << age << endl;
cout << " Height: " << height << endl;
}

int main()
{
	MyClass example;
	example.SetName();
	example.SetAge();
	example.SetHeight();
	example.PrintAll();


return 0;
}

Hey thanks very much soyunlocofl. i didnt know about the string class. thats very conveinient. do you happen to know a way to do it without using the string class? im just not sure how to pass the arguments to the member functions to set the name. thanks again.

Class MyClass

Simple example but remember that the keyword for declaring a class is

class

Not sure if this is what you were looking for, but I prefer this way ('Cause it's much easier):
