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

SCHAR_MIN constant is a macro constant which is defied in climits header, it is used to get the minimum value of a signed char object, it returns the minimum value that a signed char object can store, which is -128.

SCHAR_MIN常量是在climits标头中定义的宏常量，用于获取签名char对象的最小值，它返回签名char对象可以存储的最小值-128 。

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 SCHAR_MIN constant is defined in both of the libraries.

  我们还可以使用<limits.h>头文件而不是<climits>头文件，因为在两个库中都定义了SCHAR_MIN常量 。

Syntax of SCHAR_MIN constant:

SCHAR_MIN常量的语法：

SCHAR_MIN

Example:

例：

Constant call:    cout << SCHAR_MIN;    Output:    -128
