chars

[Bill Cunningham]

OK this thing about chars. So a string and a char is two different
things. This is the way I'm understanding things:

char c; is actually a short or int
char *s; s is a pointer to a char and to be used for strings
char foo[5]; is an array used to store so much info.

Do I sound like I'm getting it right now?

No. A char is a char. That is one integer type in C. short is another.
int is another. They are not the same types.

char *s; s is a pointer to a char and to be used for strings

It can be set to point to a string. It doesn't need to. This is
perfectly valid C:

char *s;
char c = 'A';

s = &c;

*s = 'B';

It could set to point to a string literal:

s = "string";

However, that is bad programming practice.

It could point to allocated storage, that might contain a string:

s = malloc(5); /* skipping error check */
strcpy(s, "Hi!");

char foo[5]; is an array used to store so much info.

It is an array of char. It might hold string. It would limited to a
string length of four.

I was just letting you know where I am getting my information.

Well, that's a decent tutorial. Whether you're getting it or not is
another question (hence, "reply hazy").
