Suppose you want to remove extra spaces at the begnning or end of a string. Java has the trim() method to do this, but C++ does not. However, you can use the substr() member function, along with the two member functions find_first_not_of(() and find_last_not_of() to write your own. 1. Find the position of the first non-space character. 2. Find the position of the last non-space character. 3. Use substr(() to produce a new string.
