Pointers lay the foundation of C programming, offering direct memory access and manipulation capabilities that are both powerful and complex. As we delve deeper into pointers, we encounter double pointers, an extension of the basic pointer concept. Do

- 有符号整型:可以表示正整数、负整数和零。例如在C/C++ 中, int 通常占4个字节(32位),能表示的范围是-2^{31}到2^{31}-1; long 可能占4字节或8字节,具体取决于编译器和系统,范围也相应不同; short 一般占2个字节,范围是-2^{15}到2^{15}-1。
