|
The C++ source code character set is a superset of the ISO 646-1983 Invariant Code Set. To enable you to use only the reduced set, you can use trigraph sequences to represent those characters not in the reduced set. A trigraph sequence is a set of three characters that is replaced by a corresponding single character. The preprocessor replaces all trigraph sequences with the corresponding character. Table 2-2 “Trigraph Sequences and Replacement Characters” gives the complete list of trigraph sequences and their replacement characters. |
