Does this make sense to you guys? In my book it says that if you declare a variable as an integer constant, and you need it to be stored as a long, you can force and integer constant to be stored as a long by placing the letter L at the end of the number...

like this:

1337L

My question is, why wouldn't you just declare the variable as a long in the first place?

Hmm.... can't think of a better example right now.... but here's one case where you might need it:

You have 2 functions overloaded with different signatures:
Code:

void kill (int in);
void kill (long in);


Although having the same name, your two functions perform completely different tasks.

Now, let's say you want to call the long function with a constant. You now could do kill(123L) instead of declaring a long variable then pass that in.
