# Description:
#   This file contains python code that asks the user for
#   their major and grade, and prints out whether they are
#   eligible to move on to CMSC 202 in the next semester.

#   This version uses nested decisions, with the 
#   student's grade as the outer decision.

def main():

    # get major and grade from the user
    major = input("Please enter your major: ")
    grade = input("Please enter your grade: ")

    # for everyone, an A or B counts as passing the class
    if grade == "A" or grade == "B":
        print("You can take CMSC 202!")

    elif grade == "C":
        # for CMSC and CMPE majors, a C is not enough to pass
        if major == "CMSC" or major == "CMPE":
            print("You cannot move on to CMSC 202.")
        # for all other majors, a C is enough
        else:
            print("You can take CMSC 202!")

    # any other grade does not count as passing, regardless of major
    else:
        print("You cannot move on to CMSC 202.")
