std::basic_...ng::max_size(3) C++ Standard Libarystd::basic_...ng::max_size(3) NAME std::basic_string::max_size - std::basic_string::max_size Synopsis size_type max_size() const; (until C++11) size_type max_size() const noexcept; (since C++11) (until C++20) constexpr size_type max_size() const noexcept; (since C++20) 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> #include <climits> int main() { std::string s; std::cout << "Maximum size of a string is " << s.max_size() << " (" << std::hex << std::showbase << s.max_size() << "), pointer size: " << std::dec << CHAR_BIT*sizeof(void*) << " bits\n"; } Possible output: Maximum size of a string is 9223372036854775807 (0x7fffffffffffffff), pointer size: 64 bits See also size returns the number of characters length (public member function) max_size returns the maximum number of characters (C++17) (public member function of std::ba- sic_string_view<CharT,Traits>) http://cppreference.com 2022.07.31 std::basic_...ng::max_size(3)
