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