Need help with class

I have a question about classes.

here is my situation. I have 2 classes in 2 separate header files.

Code:

---

class a {

function
int x(int);
void y();
};
function void z();

class b {

function r;
};
function s;

---

class a in a.h file. All class a functions are in a.cpp file
I have
int a::x(g)
class b c;

Inside this function, I want to call r,s,y and z.

The question is How can I call these 4 functions.

Please have a look at how to define functions in C++:

Code:

---

<return type> <function-name>(<arguments>);

---

If the functions you implemented are not static, you first need to create an object of that class before you can call any functions.

Code:

---

A *objectOfA = new A();
objectOfA->x(10);
// ...
// delete object afterwards
delete objectOfA;

---

Why do you need to call new?
This should suffice:

Code:

---

A ObjectOfA;
ObjectOfA.x(10);
