std::basic_string::max_size

性病：基本[医]字符串：最大值[医]大小

size_type max_size() const;​​

返回字符串由于系统或库实现限制而能够保存的最大元素数，即std::distance(begin(), end())最大的字符串。

参数

%280%29

返回值

最大字符数。

例外

(none)(until C++11)
noexcept specification: noexcept(since C++11)

复杂性

常量。

例

二次

#include <iostream>
#include <string>
 
int main()
{
    std::string s;
    std::cout << "Maximum size of a string is " << s.max_size() << "\n";
}

二次

可能的产出：

二次

Maximum size of a string is 4294967294

二次
