int max+1小于0

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標頭中定義的宏常量，用于獲取帶符號的int對象的最大值，它返回帶符號的int對象可以存儲的最大值，即2147483647 (在32位編譯器上)。

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 INT_MAX constant is defined in both of the libraries.

  我們也可以使用<limits.h>頭文件代替<climits>頭文件，因為在兩個庫中都定義了INT_MAX常量 。

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

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

Output

輸出量

INT_MAX: 2147483647

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

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

Output

輸出量

INT_MAX: 2147483647
