Testing & Identifying Errors

Task #1: Checking if number within a range.

Write some code that inputs a number (already done for you), and checks whether it's between 1 and 10. If it is, then thank the user via a suitable message, otherwise alert them that their number has been rejected.

Task #2: Checking if string is within an allowed length range

Write some code that inputs a string (already done for you), and checks whether it's between 5 and 15 characters. If it is, then thank the user via a suitable message, otherwise alert them that their input has been rejected.

Task #3: Checking whether input word is an animal.

Write some code that inputs a string (already done for you), and checks whether it is the name of a farmyard animal, notably: a cow, horse, pig or goose. You should raise an error if it isn't, and you check shouldn't be case sensitive, e.g. "cow" or "Cow" or "COW" would all be accepted.

Task #4: Checking whether the input is alphanumeric.

An alphanumeric character is either a letter (whether uppercase or lowercase) or a digit (0-9). Write a function that checks whether the input consists only of alphanumeric characters. Your function should return either true or false.

Task #5: Checking a sort code.

Bank sort codes help identify the bank and branch of the bank account, e.g. "Halifax bank in Kingston-upon-Thames". These are of the form XX-XX-XX where each X is a digit, for example 49-30-03. All bank accounts for IngallBank start with 40. Write a function that determines whether the input is a valid IngallBank sort code.
