Using C$++,$ Write a program that stores $20$ names in a vector of strings, rather than in an array of strings. Create the vector without specifying a size and then use the push$\_$back member function to add an element holding each string to the vector. The data should be read in from a file. Instead of assuming there are always $20$ strings, read in the strings and add them to the vector until there is no data left in the file. The data can be found in the attached names.txt file. Once the names are read in$,$ the names should be sorted. Display the original list of names and then the sorted list of names.
