what is class in c++ code example

Example 1: how to write a class in c++

class Rectangle 
{
	int width, height;
public:
	void set_values (int,int);
    int area() {return width*height;}
};

void Rectangle::set_values (int x, int y)
{
	width = x;
	height = y;
}

Example 2: classes c++

class Rectangle {
    int width, height;
  public:
    void set_values (int,int);
    int area (void);
} rect;

Example 3: classes c++

class class_name {
  access_specifier_1:
    member1;
  access_specifier_2:
    member2;
  ...
} object_names;

Example 4: create class instance c++

MyClass* MyObject = new MyClass();

Example 5: c++ classes

class MyClass {       
  // The class
  public:             
  // Access specifier
    int myNum;        // 
  Attribute (int variable)
    string myString;  // 
  Attribute (string variable)
};

Example 6: class cpp

class Exemple
{
  private:
  	/* data */
  public:
  	Exemple(); //Constructor
  	~Exemple(); //Destructor
};
