Characters

In C, single characters are written enclosed by single quotes. This is in contrast to strings of characters, which use double quotes ("...").

int ch;
ch = 'a';

would give ch the value of the character a. The same effect can also be achieved by writing:

char ch = 'a';

It is also possible to have the type:

unsigned char

This admits ASCII values from 0 to 255, rather than -128 to 127.
