C ++ INT_MAX宏常量 (C++ INT_MAX macro constant)

INT_MAX constant is a macro constant which is defied in climits header, it is used to get the maximum value of a signed int object, it returns the maximum value that a signed int object can store, which is 2147483647 (on 32 bits compiler).

INT_MAX常量是在climits标头中定义的宏常量，用于获取带符号的int对象的最大值，它返回带符号的int对象可以存储的最大值，即2147483647 (在32位编译器上)。

Note:

注意：

• The actual value depends on the compiler architecture or library implementation.

  实际值取决于编译器体系结构或库实现。

• We can also use <limits.h> header file instead of <climits> header as INT_MAX constant is defined in both of the libraries.

  我们也可以使用<limits.h>头文件代替<climits>头文件，因为在两个库中都定义了INT_MAX常量 。

Syntax of INT_MAX constant:
