In C++, Define struct StudentInfo; maintain records in a vector<StudentInfo>. Program prompts for and fetches data, builds vector of student records, sorts by name, calculates max and min grades (no names, just max and min numbers), class average, prints summarizing data along with class roll and grades. Test program. Note: add constructors (default/parameterized wherever applicable)
