Write a method called is1to1 that accepts a map whose keys and values are strings as its parameter and returns true if no two keys map to the same value. For example, {Marty=206– 9024, Hawking=123–4567, Smith=949–0504, Newton=123–4567} should return false, but {Marty=206–9024, Hawking=555–1234, Smith=949–0504, Newton=123–4567} should return true. The empty map is considered 1-to-1 and returns true.
Write a program that keeps a map in which both keys and values are strings—the names of students and their course grades. Prompt the user of the program to add or remove students, to modify grades, or to print all grades. The printout should be sorted by name and formatted like this: Carl: B+ Joe: C Sarah: A

a. Write a function arrayToMap that takes an array of strings and returns a std::map<int, string> such that the values in the map are the string values in the array of strings, and the keys in the map are the corresponding array indices of the string values. You may assume all necessary libraries have been included in your program and your solution must be syntactically correct in order to receive full credit. map<int, string> arrayToMap(string arr[], int arrSize) { b....
