MB_LEN_MAX constant is a macro constant which is defied in climits header, it is used to get the maximum number of bytes in a multibyte character, for any locale, it returns maximum number of bytes that a multibyte character, which is 1 or more than it.
MB_LEN_MAX常数是在climits标头中定义的宏常数,用于获取多字节字符中的最大字节数,对于任何语言环境,它都返回一个多字节字符的最大字节数,即大于或等于1 。
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 MB_LEN_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MB_LEN_MAX常量 。
Syntax of MB_LEN_MAX constant:
MB_LEN_MAX常数的语法:
MB_LEN_MAX
Example:
例:
Constant call: cout << MB_LEN_MAX; Output: 16
// C++ code to demonstrate example of // MB_LEN_MAX constant with climits header#include#include using namespace std;int main(){ //prinitng the value of MB_LEN_MAX cout<<"MB_LEN_MAX: "< <
Output
输出量
MB_LEN_MAX: 16
// C++ code to demonstrate example of // MB_LEN_MAX constant withheader file#include #include using namespace std;int main(){ //prinitng the value of MB_LEN_MAX cout<<"MB_LEN_MAX: "< <
Output
输出量
MB_LEN_MAX: 16
