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:

INT_MAX常量的语法：

    INT_MAX

Example:

例：

    Constant call:
cout << INT_MAX;
Output:
2147483647

C ++代码演示带有climits标头的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_MAX
cout<<"INT_MAX: "<<INT_MAX<<endl;
return 0;
}

Output

输出量

INT_MAX: 2147483647
