The name of the C+ file must be sortNames.cpp Write a program that will read names from the file "names.dat". The names read from the file should be stored into a string array of size 20. The program must use the insertion sort algorithm to sort the array of strings. main will first display the unsorted names, call the sorting function, and then display the sorted array. Hint: You will need to use getline member function to read names from file into the string array (i.e. getline (inputFile, array[index])
