Short integer: short integer 2 bytes.

Long integer: Long integer 4 bytes.

Unsigned integer shaping: unsigned integer 2 bytes.

Unsigned short integer: unsigned short integer 2 bytes.

Unsigned long integer: unsigned long integer 4 bytes.

Single-precision floating-point 4 bytes with 7 significant digits

Double 8-byte significant digits 16 bits

Char type char 1 byte

The above is the doubling of 32 bits in 16-bit computer system.

If you really don't believe it, you can use the sizeof function to verify it. The method is as follows

# contains "stdio.h"

Master ()

{

int m；

M=sizeof (data type);

printf("%d "，m)；

}
