//Programming exercise:
//        Grades and Points
//        Points
//        1/1
//
//        The table below describes how the grade for a particular course is determined.
//        Write a program that gives a course grade according to the provided table.
//
//        points grade
//        < 0    impossible!
//        0-49   failed
//        50-59	 1
//        60-69	 2
//        70-79	 3
//        80-89	 4
//        90-100 5
//        > 100	 incredible!
//
//////////Sample outputs://////////
//
//        Sample output
//
//        Give points [0-100]:
//        37
//        Grade: failed
//        Sample output
//
//        Give points [0-100]:
//        76
//        Grade: 3
