Date Types:
how many memory cells are reserved for it
- Integers
- short (2 bytes – 16 bits)
- int (2 bytes?)，64位机中为4 bytes
- long 32 bits (4 bytes)
- unsigned (2 bytes)
- unsigned short (2 bytes)
- unsigned long 32 bits (4 bytes)
- Floating Points
- float (4 byte, or 32 bits)
- double (8 bytes, or 64 bits)
- Characters
- 1 byte
- （128 distinct characters in the ASCII character set.）
- （Two C character types:
• char (1 byte or 8 bits, range: [–128, 127]
• unsigned char (1 byte or 8 bits, range: [0, 255]）
- Integers

ASCII:
++i 返回值是（i+1）；i++返回值是i （先加再返回和先返回再加）（返回指表达式值）
const
#define 替换
