Setting Char variables

Question

For a char variable would i also set it to 0 as i would set and int or a float or any other variable?

Such as

char test = 0

would it be like that since

int test = 0

would be like that?

What are you actually trying to accomplish? What are you going to do with it after you "clear" it? Store another value? Print it? — Cascabel

Which do you want? The character '0', or the ascii 0?

If you want to set it to the character '0', then you need:

char test = '0';

If you want the ascii value 0, then it's fine the way it is.

I just want it to be cleared with nothing. Basically as int would be 0 yeah.

Variables don't really need to be "cleared". If you're going to write to it on the first use, you don't need to initialize it to anything.

More strongly, char and int values cannot be cleared, they always contain a valid value.

So i can literally use char test; and thats it?

Mysticial Over a year ago

Correct. It doesn't need to be initialized.

You can always use type conversions in c++, so even if you write int test = 0 you can access its ascii by converting it into char, this goes without saying for chars
