Here's another approach using a while loop to check for the end of the string: // Within this function, `line` is initially a pointer to the first // char in a string (Null terminated char array). Read the entered string using gets() function and store the string into s1. Store it in some variable say str1 and str2. template <class InputIterator> void insert (InputIterator first, InputIterator last); It accepts a range of input iterators and one by one all the elements in set while traversing through the range( first to last-1).
