Thread: Classes Question.

So, im ok understanding the classes from this tutorial -Classes in C++ - Cprogramming.com, but what i can't understand and im so curious about it, how to use Strings in classes? For example:

Code:

#include <iostream>


using namespace std;




class Computer
{
public:
	Computer();
	//Constructor


	~Computer();
	//Destructor


	void setSpeed (int p);
	int readSpeed();


	void setMemorySpeed(int r);
	int readMemorySpeed();
protected:
	int normalSpeed;
	int memorySpeed;
};


Computer::Computer()
{
	normalSpeed = 0;
	memorySpeed = 0;
}
Computer::~Computer()
{




}


void Computer::setSpeed(int p)
{
	normalSpeed = p;
}
int Computer::readSpeed()
{
	return normalSpeed;
}


void Computer::setMemorySpeed(int r)
{
	memorySpeed = r;
}
int Computer::readMemorySpeed()
{
	return memorySpeed;
}




int main()
{
	Computer compute;


	compute.setSpeed(150);
	compute.setMemorySpeed(512);


	cout<< "Your normal speed is: " << compute.readSpeed() << "\n"
		<< "Your memory speed is: " << compute.readMemorySpeed() << "\n";
	cin.get();
}

Here is the output: .

Now, what i want is: a String that shows for example: Your Computer OS type is: Windows XP - SP3.

Thank you infront.

#include <string>

using namespace std;
 
class myString{
private:
    string str;
public:
    string example(){ return "Example string"; }
};
int main() 
{
    myString eg;
    cout << eg.example() << endl;
    return 0;
}

I suggest you take a look at the std::string class.

But what if i want to make another object of the same class to be with different returns? Like object myString eg is gonna return "Example string", now myString eg1 for example is going to return the same quotes , how can you change the arguments for each object created? Like the changing of the integers above in my code. Ty

same as integer - pass it to constructor of the class or create some setter member function which will accept string and store it in the member variable

How am i supposed to create a Setter member function which accept string? Thats im wondering all the time
