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標頭中定義的宏常量，用于獲取簽名char對象的最小值，它返回簽名char對象可以存儲的最小值-128 。

Note:

注意：

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

  實際值取決于編譯器體系結構或庫實現。

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

  我們還可以使用<limits.h>頭文件而不是<climits>頭文件，因為在兩個庫中都定義了SCHAR_MIN常量 。

Syntax of SCHAR_MIN constant:

SCHAR_MIN常量的語法：

SCHAR_MIN

Example:

例：

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

C ++代碼演示帶有climits標頭的SCHAR_MIN常量示例 (C++ code to demonstrate example of SCHAR_MIN constant with climits header)

// C++ code to demonstrate example of // SCHAR_MIN constant with climits header #include<iostream> #include<climits> using namespace std;int main() {//prinitng the value of SCHAR_MINcout<<"SCHAR_MIN: "<<SCHAR_MIN<<endl;return 0; }

Output

輸出量

SCHAR_MIN: -128

C ++代碼演示帶有limits.h頭文件的SCHAR_MIN常量示例 (C++ code to demonstrate example of SCHAR_MIN constant with limits.h header file)

// C++ code to demonstrate example of // SCHAR_MIN constant with <limits.h> header file #include<iostream> #include<limits.h> using namespace std;int main() {//prinitng the value of SCHAR_MINcout<<"SCHAR_MIN: "<<SCHAR_MIN<<endl;return 0; }

Output

輸出量

SCHAR_MIN: -128
