Thread: Why Classes??

I have read about using Class But I doesn't understand Why to use Class??
I mean if I will creat a Class that contain 2 funcs and 5 varibles
what will be worse if I creat 2 func and 5 varibles outside a class
and not useing class???
[ I does not refuse using Classes But doesn't understand Why?]

Because if you 'write' a class to do a specific task(such calculate the surface of a circle) and you need it someday in another project, well the class you've wrtie will work in any programs.... if you don't do it in a class, well you'll have to re-write everything to make it fit into your program....

a class is reusable...

One nice thing is that you can do this:

Code:

class c {
int anint;
char array[50];
void func();
int func2(int a);
};

//and then do

c classarray[50];

//instead of creating 50 of each variable and function
