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

NAME

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

Synopsis


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
