MPLAB IDE数据类型大小

Question

在MPLAB IDE是什么数据类型(的大小int,unsigned int,float,unsigned float,char...)？

Answer 1

如果不知道要编译代码的CPU,这很难.假设用于PIC18的Microchip的C18编译器,用户指南指出了以下基本类型大小:

TYPE                SIZE     RANGE
char(1,2)            8 bits  -128 127
signed char          8 bits  -128 127
unsigned char        8 bits  0 255
int                 16 bits  -32,768 32,767
unsigned int        16 bits  0 65,535
short               16 bits  -32,768 32,767
unsigned short      16 bits  0 65,535
short long          24 bits  -8,388,608 8,388,607
unsigned short long 24 bits  0 16,777,215
long                32 bits  -2,147,483,648 2,147,483,647
unsigned long       32 bits  0 4,294,967,295

请注意,这包括一些short long在C中不标准的类型().
