      void push_back(const T& value);

      void push_back( T&& value);
      (2)(since C++11)
      (constexpr since C++26)

      Appends a copy ofvalue to the end of the container.

      No iterators or references are invalidated.

      [edit]Parameters

      value - the value of the element to append

      Type requirements
      -
      If the following condition is met, the behavior is undefined:
      1)T is notCopyInsertable intolist.
      2)T is notMoveInsertable intolist.
      (since C++11)

      [edit]Complexity

      Constant.

      [edit]Exceptions

      If an exception is thrown (which can be due toAllocator::allocate() or element copy/move constructor/assignment), this function has no effect (strong exception guarantee).

      [edit]Example

      Run this code
      #include <iomanip>#include <iostream>#include <string>#include <list> int main(){std::list<std::string> letters;     letters.push_back("abc");std::string s{"def"};    letters.push_back(std::move(s)); std::cout<<"std::list letters holds: ";for(auto&& e: letters)std::cout<<std::quoted(e)<<' '; std::cout<<"\nMoved-from string s holds: "<<std::quoted(s)<<'\n';}

      Possible output:

      std::list letters holds: "abc" "def"Moved-from string s holds: ""
