Design the following menu-driven application using C++ Vector class. Implement the following five functions 1. Add(vectorcchar> &ch) Prompts th ser to provide a character and add that character int the vect r 2. Remove(vectorcchar> &ch) Prompts the user to provide a character. If the character is found in the vector, it removes that character. Otherwise, it generates a message 3. Show(vectorcint &num) sh w the existing members f the vector ( rder d matter) It wi11 generate a message if it is empty n t Sample output: Add a character Renove a character Show the characters Quit dd a character Remove a character Show the characters Quit Lease enter a choice: 2 Lease enter the character: he character was not found Add a character Remove a character Sho the characters Quit Lease enter a choice: 1 Lease enter the character: a Please enter a choice:3 Add a character Renove a character Show the characters Quit Add a character Remove a character Show the characters Quit Lease enter a choice: 1 Lease enter the character: b Lease enter a choice: 2 Lease enter the character: a he character has been removed
