std::basic_string
 
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

Run this code
#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
