The range of short integer data in C language is -32768----32767 is in--32768 is how to determine

Short shaping on 32-bit PCs is 2 bytes, each byte is 8 binary bits, a total of 16 bits
16 bits, can represent the number of numbers is 0 ~ 2^16-1, that is 0 ~ 65535 a total of 65,536, if the positive and negative integer each half, That is a negative integer-32768 ~-1, a total of 32,768, 01, positive integer 1 ~ 32767 total 32,767, altogether 65,536.

The short, int , and   long  types all represent integer values with different sizes of storage space. General,  short  type is half machine word length, int  type is one machine length, and   long  type is one or two machine words (in  32  bit machine   INT   Type and   long  types usually have the same word length.   unsigned    int    0~4294967295                     is 2^32-1 int   - 2147483648~2147483647                       is 2^ ( -31)  ~ 2^31-1 unsigned  long  0~4294967295                         is 2^32-1 long   -2147483648~2147483647                      is 2^ ( -31)  ~  2^31-1 long  long Max: 9223372036854775807            is 2^63-1 long  long.
