Overview of the primitive data types of C

---

• C's built-in data types that are similar to ones in Java

  Syntax	Name	Java's counterpart	use
  char	character	byte	Stores an ASCII code (character) or it can also store a very short integer (−128..127)
  short	short integer	short	uses 2 byte memory, value between −32768 and 32767
  int	ordinary integer	int	uses 4 byte memory, value between −2147483648 and 2147483647
  long	long integer	long	uses 8 bytes memory, value between −9223372036854775808 and 9223372036854775807
  float	single precision float	float	uses 4 byte memory, absolute value between 1.4E−45 and 3.4E38
  double	double precision float	double	uses 8 byte memory, absolute value between 4.9E−324 and 1.8E308
  _Bool	boolean	boolean	true (1) or false (0)

• C's built-in data types that do not have an equivalent in Java

  Syntax	Name	use
  unsigned char	Unsigned character	Very short positive integer (0..255)
  unsigned short	Unsigned short integer	uses 2 byte memory, value between 0 and 65535
  unsigned int	Unsigned ordinary integer	uses 4 byte memory, value between 0 and 4294967295
  unsigned long	Unsigned long integer	uses 8 bytes memory, value between 0 and 18446744073709551615
  *	Reference type	Contains a memory address (usually 4 bytes, but 64 bits machines will use 8 bytes)
