c#中的long类型示例

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

LONG_MAX constant is a macro constant which is defied in climits header, it is used to get the maximum value of a long int object, it returns the maximum value that a long int object can store, which is 9223372036854775807 (on 32 bits compiler).

LONG_MAX常量是在climits标头中定义的宏常量，用于获取long int对象的最大值，它返回long int对象可以存储的最大值，即9223372036836854775807 (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 LONG_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LONG_MAX常量 。

Syntax of LONG_MAX constant:

LONG_MAX常数的语法：

    LONG_MAX

Example:

例：

    Constant call:
    cout << LONG_MAX;

    Output:
    9223372036854775807

C ++代码演示带有climits标头的LONG_MAX常量示例 (C++ code to demonstrate example of LONG_MAX constant with climits header)

// C++ code to demonstrate example of 
// LONG_MAX constant with climits header
#include<iostream>
#include<climits>
using namespace std;

int main()
{
   //prinitng the value of LONG_MAX
    cout<<"LONG_MAX: "<<LONG_MAX<<endl;
    return 0;
}

Output

输出量

LONG_MAX: 9223372036854775807

C ++代码演示带有limits.h头文件的LONG_MAX常量示例 (C++ code to demonstrate example of LONG_MAX constant with limits.h header file)

// C++ code to demonstrate example of 
// LONG_MAX constant with <limits.h> header file
#include<iostream>
#include<limits.h>
using namespace std;

int main()
{
   //prinitng the value of LONG_MAX
    cout<<"LONG_MAX: "<<LONG_MAX<<endl;
    return 0;
}

Output

输出量

LONG_MAX: 9223372036854775807
