typedef signed char int8_t; typedef short int16_t; typedef int int32_t; typedef long long int64_t; 用于区分该整数占用几个字节,在实际开发中,可以直接使用标准库中的类型:int8_t、int16_t、int32_t、int64_t,其中int8_t占用1个字节,int16_t占用2个字节,int32_t占用4个字节,int64_t占用8个...

The space savings possible with (small-valued) subrange types in Pascal and Ada is achieved in several other languages by providing more than one size of built-in integer type. C and C++, for example, support integer arithmetic on signed and unsigned variants ofchar,short,int,long, and (in...
在上面的demo程序中,我们声明了一个数组类型array_t,然后再使用该类型定义一个数组array,这个array效果其实就相当于:int array[10]。 1.3 typedef 与指针的结合使用 typedef char * PCHAR; int main (void) { //char * str = "学嵌入式"; PCHAR str = "学嵌入式"; ...
这些归功于 typedef ，对名字编程。有的编译器认为 long int 相对 short int 而言的，所以 long int ...
