Write a C$++$ program to play one or more random number games.$$

Put a program description and your name in code comments at the top.

$$

The program asks users to enter three single characters separated by spaces $(1$ or more$),$ and depending on the characters, it will generate a random number.

$$

Here are the rules to follow exactly:

$-$ If the input character is exactly $\text{'}$a$\text{'},$ the program will generate a random number from $1$ to $20.$

$-$ If the input character is exactly $\text{'}$e$\text{'},$ the program will generate a random number from $21$ to $40.$

$-$ If the input character is exactly $\text{'}$i$\text{'},$ the program will generate a random number from $41$ to $60.$

$-$ If the input character is exactly $\text{'}$o$\text{'},$ the program will generate a random number from $61$ to $80.$

$-$ If the input character is exactly $\text{'}$u$\text{'},$ the program will generate a random number from $81$ to $100.$

$-$ If the input character is not one of the above characters, generate a $0$ in the output.

$$

Notes:

$1-$ Inputs should only be lower$-$case letter vowels to be considered valid. Any other characters should show $0.$

$2-$ Program should not calculate any random numbers before checking the input characters.

$3-$ Program should calculate only one random number for each input vowel.

$4-$ Each input character should be used to create a separate output. For example, if the inputs are $"$a a a$",$ the outputs would be three independent and different random numbers in the range of $1$ and $20.$ Do not use the same random number for all $3$ inputs.

$5-$ It's expected that the program will have $3$ character inputs and $3$ separate "switch" statements that are very similar to each other for each game.

$6-$ After each game, the program asks users to see if it should play another game. If users want to play another game, users answer with $\text{'}$y$\text{'}$ or $\text{'}$Y$\text{'}.$ The program should be able to handle any character answer other than $\text{'}$y$\text{'}$ or $\text{'}$Y$\text{'},$ including whitespaces.

Here are some sample runs:

This program plays a simple random number game.

Enter $3$ lower vowel characters $($a$,$e$,$i$,$o$,$u$)$ separated by spaces: a e i

The random numbers are $52445$

Do you want to play again? y

Enter $3$ lower vowel characters $($a$,$e$,$i$,$o$,$u$)$ separated by spaces: A a u

The random numbers are $0888$

Do you want to play again? y

Enter $3$ lower vowel characters $($a$,$e$,$i$,$o$,$u$)$ separated by spaces: b o i

The random numbers are $06856$

Do you want to play again? n
