Write in C++ Project Euler: Name Scores Problem 22 (external link) Using resources/names.txt, a text file containing over five thousand first names, begin by sorting it into alphabetical order. Then, work out the alphabetical value for each name. Multiply this value by its alphabetical position in the list to obtain a name score. For example, when the list is sorted into alphabetical order, COLIN has an individual score of 53, and he is ranked 938th in the list, for a total score of 49,714. COLIN = C:3 + O:15 + L:12 + I:9 + N:14 = 53 Ranking = 938 * 53 = 49,714 Score = 49,714 What is the total of all the name scores in the file? In the main.cpp file given, complete the program as specified. The program must utilize arrays and either the bubble sort or selection sort algorithm. Output the answer: What is the total of all the name scores in the file?
