How do you assign an octal value to a number?

Assigning an octal value to a variable is as easy as assigning a hexadecimal value to a variable, except that you
need to know the octal numbering system in order to know which numbers to assign.

int x;
x = \033; /* put octal 33 (decimal 27) into x */
x = ‘\033’; /* put the ASCII character whose value is
octal 33 into x */
Refer to FAQ XX.23 for detailed information on the octal numbering system.
