The program needs to display the average in decimal form (numerically and textual) and in hexadecimal form(numerically). Instruction for the user: "Give the interval (lower, upper):' Scores: criteria check --> 10 calculate the average --> 15 conversion to hexadecimal --> 15 conversion to text --> 10 For example: Input Result Give the interval (lower, upper): 1,30 15 five one F Give the interval (lower, upper): 210,299 254 two five four FE Give the interval (lower, upper): -15,190 88 eight eight 58
