title: Overloading the " - " (minus) operator in c++ to work with a string?
body: <p>I was looking into how to use operator overloading in c++ to work with classes but could not get a clear idea online so I'm posting this question.I want to basically overload the minus "-" operator to remove a sub-string from a bigger string, . Example is the first string is "Hello World" and the second string is "He", the output should be "llo World". </p>
