I'm having trouble writing a class.

Okay, I have been learning about using classes, now I want to write my own.

I read how to do it in various textbooks and this is what I came up with:

Code:

---

#include <iostream.h>
#include <stdlib.h>

class Myclass
{
public:
  Myclass()
  {
    value = 0;
  }

  Myclass(int x)
  {
    vlaue = x;
  }
 
  void print()
  {
    cout<<value;
  }
 
  void set(int x)
  {
    value = x;
  }
private:
  int value;
};

void main()
{
  int number;
  Myclass test;
  test.print();
  cout<<"Enter a new value: ";
  cin>>number;
  test.set(number);
  test.print();
  cin.get();
}

---

Now I know the class definition is usually in a seperate file which is included, but it's meant to work like this too isn't it?

When I try to complile this code in Bloodshed Dev-C++ I get an error at the line

Code:

---

    value = 0;

---

telling me

Quote:

---

9 h:\myclass.cpp `value' undeclared (first use this function)

---

What's wrong?
Am I totally ont he wrong track or is it just a typo or small syntax error?

Code:

---

Myclass(int x)
  {
    vlaue = x;
  }

---

You have value spelled wrong.

-DIS

Agreed.

Such as it is, it runs fine after that correction.

:)

THANK YOU!

Oh, I tried this about 5 times!
In different places, with different code.

And EVERY time, it didn't work.
I really gotta be careful of those typso...

Don't think you'd be the frist...fsrit...first.

:)

Try to become familiar with the error messages that the compiler spits out. Some are very cryptic but that would probably be an undeclared identifer error which will point you to the line or even the word, depending on your compiler.

After a while you wont even need to read the whole error, just going to the line will make it obvious :)
