Real-Life Programming Examples
public:
private:
};
Underneath both the public and private keywords, you must declare
your data and subprograms. If you wanted to define an X coordinate and
Y coordinate variable as public and an X variable as private, you’d do
this:
class animal
{
public:
int x_coordinate;
int y_coordinate;
private:
int x;
};
Not all objects have both public and private data and subprograms. Some
objects may just have public data and subprograms.
The preceding code creates three integer variables — x_coordinate,
y_coordinate, and x. After you define the data your object will use, the
next step is to define the subprograms it’ll use, such as
class animal
{
public:
int x_coordinate;
int y_coordinate;
void initial_position (int, int);
void move(int, int);
private:
int x;
};
The preceding code defines two subprograms (methods) — initial_
position and move. The initial_position and move subprograms both
accept two integers in their parameter list. After you define the names of the
subprograms you want to use, you have to write the actual code to make
each subprogram work, such as
class animal
