std::basic_string<CharT,Traits,Allocator>::max_size

size_type max_size() const;
(until C++11)
size_type max_size() const noexcept;
(since C++11)

Returns the maximum number of elements the string is able to hold due to system or library implementation limitations, i.e. ​std::distance(begin(), end())​ for the largest string.

Parameters

(none).

Return value

Maximum number of characters.

Complexity

Constant.

Example

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

Possible output:

Maximum size of a string is 4294967294
