If and While Preceeding Switch Statements and Clashing

JoJodoggy1 (52)
I hope you can see what I am trying to do using my comments) the statements/commands are clashing into each other and no matter how I have tweaked things and changed brackets around, something always clashes into the other.

Psuedocode:

Prompt user to enter a letter that corresponds to a digit on the phone.

Input user’s choice.

Use do-while so when the user enters anything other than $, the program will run. $ will terminate the program.

If the user enters a lower case letter, prompt the user that the letter is lower case and then convert it to uppercase and print out the corresponding number.

Use while for user enters a q, Q, z, or Z prompt that those letters are not on the phone and allow them to reenter a new choice until they enter something valid. Also, negate the output for the lower to uppercase letter conversion to the user

If the user enters a special character, prompt that the program will not accept these and allow them to reenter a new choice until they enter something valid.

Well, what you can do is break the comments into two lines- make it so that half of it (or more) carries over in the same indentation: like this:
1
2
3
4
5
6
7
8
 
//command to prompt user to enter a new choice if they enter these characters until they enter something valid
		while (choice == 'q' || choice == 'Q' || choice == 'z' || choice == 'Z')//while the user enters any of these chars...
		{
			!((char)toupper(choice));                                       //negate output that letter will be made uppercase
			cout << "No digit corresponds to" << choice << endl;            //they will be prompted to re-enter a new choice until they enter something valid
			cout << "Enter a new letter";
			cin >> choice;
		}


Also, you can break those massive while-based truth testing for user input into multiple lines- whitespace means nothing except in strings and template-templates, after all.
