* |
Integer. Its length traditionally depends on the length of the system's Word type, thus in MSDOS it is 16 bits long, whereas in 32 bit
systems (like Windows 9x/2000/NT and systems that work under protected mode in x86 systems) it is 32 bits long (4 bytes). |

| bool |
1 |
Boolean value. It can take one of two values: true or false
NB: Not all compilers (old ones) support bool. |
true or false |
| wchar_t |
2 |
Wide character. It is designed as a type to store international characters of
a two-byte character set.
NOTE: this is a type recently added by the ANSI-C++ standard.
Not all compilers support it. |
