매개 변수

• _P0
  The index of the position behind the point of insertion the new characters.

• _Ptr
  The C-string to be wholly or partly inserted into the string.

• _Count
  The number of characters to be inserted.

• _Str
  The string to be wholly or partly inserted into the target string.

• _Off
  The index of the part of the source string supplying the characters to be appended.

• _Ch
  The character value of the elements to be inserted.

• _It
  An iterator addressing the position behind which a character is to be inserted.

• _First
  An input iterator, const_pointer, or const_iterator addressing the first element in the source range to be inserted.

• _Last
  An input iterator, const_pointer, or const_iterator addressing the position of the one beyond the last element in the source range to be inserted.

반환 값

Either a reference to the string object that is being assigned new characters by the member function or, in the case of individual character insertions, an iterator addressing the position of the character inserted, or none, depending on the particular member function.
