Yes, there's a couple of ways to do this:

The simplest way is to use #define statements in your class header file. Any code which has access to the header file will also have access to your constants:

#define kConstant1 233
#define kConstant2 128

class SomeClass
{
...
};

Note there are no semi-colons after the constant definitions.

You can use the constants in your code like such:

int x = 10;
int y = x + kConstant1;

You can name the constants whatever you want. There are a couple of conventions for this including the one you see above whereby all constants begin with a lower-case 'k'.

There are other ways to add constants to your code. You may also want to read up on 'enum' structures.
