Basic data types in C, C++ and Java languages

  --A brief introduction to several recently popular languages ​​and their basic data types. Compare the difference! ! In fact, friends who have learned these three languages ​​know that most of them are the same, but there are a few different types. The following is my own summary:

  The first one: C language
   1. The basic types are divided into: numerical type and character type char.
       Numerical type is divided into: integer, floating point.
          Integer is divided into: short integer short, Integer int, long integer long.
          Floating point is further divided into: single-precision float, double-precision double.
   2. The structure type is divided into: array, structure struct, union union, enumeration type enum.
   3. Pointer type
   4. Empty type void

  The second: C++ language
   1. The basic type is added on the basis of C: Boolean bool. (char, short, int, long, float, double)
        Boolean has only two values: false , true;
   2. Constants are divided into: integer constants, real constants, character constants, string constants, Boolean constants, etc.
   3. Variables are quantities whose values ​​can change during execution. The
 
  third type: Java language
   1 .Numerical type is added on the basis of C: byte type byte (char, short, int, long, float, double)
   2. Logical type boolean. The
       logical type has only two values: false, true;

This is my personal opinion...
