Negative ASCII value

Question

What\'s the point of negative ASCII values?

int a = \'«\'; //a = -85 but as in ASCII table \'<<\' should be 174

Answer 1

ASCII ranges 0..127, ANSI (also called 'extended ASCII') ranges 0..255.

ANSI range won't fit in a signed char (the default type for characters in most compilers).

Most compilers have an option like 'char' Type is Unsigned (GCC).
