Exercises

Exercise 1: selecting pH values

Write a program that prompts the user to enter a pH value. Then, print an indication of whether the pH given indicates an acid (value < 7.0), base (value > 7.0) or neutral (value is 7.0) substance.

Assuming that pH values range from 0.0 to 14.0, update your program so that only valid pH values are considered.

Exercise 2: getting the highest grade

Design and implement a program that inputs student grades from three students (A to F) and prints the highest one. (To make the problem more “interesting”, don’t use the max function to solve this problem.)

Exercise 3: are you a horse?

Implement an algorithm that would take an user to a series of questions to let him know if he is a horse. The procedure will follow the flowchart:
