Programming Projects PP 8.1 Write a program that reads an arbitrary number of integers that are in the range 0 to 50 inclusive and counts how many occur- rences of each are entered. Indicate the end of the input by a value outside of the range. After all input has been processed, print all of the values (with the number of occurrences) that were entered one or more times. PP 8.2 Modify the program from PP 8.1 so that it works for numbers in the range between -25 and 25. PP 8.3 Write a program that creates a histogram that allows you to visually inspect the frequency distribution of a set of values. The program should read in an arbitrary number of integers from a text input file that are in the range 1 to 100 inclusive; then pro- duce a chart similar to the one below that indicates how many input values fell in the range 1 to 10, 11 to 20, and so on. Print one asterisk for each value entered. - 10 | ***** | ** 1 11-20 2130 ***************** 3140 41-50 *** 51-60 | 6170 ** 7180 ***** 8190 ******* 91 100 |*********
