Loop Classify

Description:

In the "Loop Classify" exercise, your objective is to create a program that continuously prompts the user to enter a single character. Depending on the character's nature, the program should classify it into one of the following categories:

$-$ Digit

$-$ Lowercase letter

$-$ Uppercase letter

$-$ Something else

The program should use a loop to continuously accept inputs and nested selection $($nested if statements$)$ to determine the classification of the entered character. The program should only terminate when the user inputs the $\text{'}\backslash (\backslash$sim $\backslash )\text{'}$ character. Upon termination, a farewell message should be displayed.

Instructions:

$1.$ The program begins by prompting the user with the message: "Type any key $($ to quit$)...".$

$2.$ Accept a single character input from the user.

$3.$ Use nested selection statements to classify the entered character:

$-$ If the character is a digit $(0-9),$ print: "That was a digit."

$-$ If the character is a lowercase letter $($a$-$z$),$ print: "That was a lowercase letter."

$-$ If the character is an uppercase letter $($A$-$Z$),$ print: "That was an uppercase letter."

$-$ If the character is the $\text{'}\backslash (\backslash$sim $\backslash )\text{'}$ or anything other than the categories mentioned above, print: "That was something else!".

$4.$ Continue to prompt the user for input until they enter the $\text{'}\backslash (\backslash$sim $\backslash )\text{'}$ character.

$5.$ After the user enters the $\text{'}\backslash (\backslash$sim $\backslash )\text{'}$ character and the appropriate message is printed, display a final message: "All done! Goodbye!".

For example:

$```$

Input Result

Type any key $($~ to quit$)...$

$>$ That was a lowercase letter.

Type any key $($~ to quit$)...$

$>$ That was a uppercase letter.

Type any key $($~ to quit$)...$

$>$ That was a lowercase letter.

Type any key $($~ to quit$)...$

$>$ That was a digit.

Type any key $($~ to quit$)...$

$>$ That was something else!

All done! Goodbye!
