-    char a single byte, capable of holding one character in the local

character set, usually 8 bits

-    intan integer, typically reflecting the natural size of integers on

the host machinę, e.g. 32 bits

-    float single-precision floating point, usually 32 bits (7 decimal digits)

-    double double-precision floating point, usually 64 bits (15 decimal dig.)

•    Qualificrs that can bc applied to thesc basie types:

-    short and long apply to integers
