- 15. Problem 1 At AUC, the academic standing of a student is determined based on the number of the credit hours that the student has achieved. The rules are as follows: Write a program in C++ to input the number of credit hours achieved by the student and print out his/her academic standing. Implement your solution in C++ once using nested-if structure and second using switch structure. Validate the user input to accept only number of credit hours that is between 0 and 133 (inclusive). Number of Credit Hours (CrH) Academic Standing CrH < 30 Freshman 30 <= CrH < 60 Sophomore 60 <= CrH < 90 Junior 90 <= CrH < 120 Senior 120 <= CrH Graduating Senior Presented by TA. Nada Kamel
