Given a map pre-filled with student names as keys and grades as values, complete main() by reading in the name of a student, outputting their original grade, and then reading in and outputting their new grade. Ex: If the input is: Quincy Wraight 73.1 the output is: Quincy Wraight's original grade: 65.4 Quincy Wraight's new grade: 73.1 #include #include #include using namespace std; int main (int argc, char* argv[]) { string studentName; double studentGrade; map studentGrades; // Students' grades (pre-entered) studentGrades.emplace("Harry Rawlins", 84.3); studentGrades.emplace("Stephanie Kong", 91.0); studentGrades.emplace("Shailen Tennyson", 78.6); studentGrades.emplace("Quincy Wraight", 65.4); studentGrades.emplace("Janine Antinori", 98.2); // TODO: Read in new grade for a student, output initial // grade, replace with new grade in map, // output new grade
