Suppose you have a collection of student records. The records are structures of the following type:

The records are maintained in a vector. Write a program that prompts for and fetches data and builds a vector of student records, then sorts the vector by name, calculates the maximum and minimum grades, and the class average, then prints this summarizing data along with a class roll with grades. (We are not interested in who had the maximum and minimum grade, though, just the maximum, minimum, and average statistics.) Test your program.
