Error on the Switch case 1

[LucianoPena28]

Currently facing an error on Case 1, where the if loop is totally ignored and from the previous interaction of user jumps to the next interaction without recognizing the if arguement.

Please help! Asking for a solution. To view the full code go to the URL: cpp.sh/9buy
It's too much code to fit in here.

If any of the data you're entering consists of more than a single word, the extraction operator (>>) is not appropriate for the task. Why are you using cin.getline in some places and not in others?

Also, if is not a loop, nor does it have arguments.

[LucianoPena28]

sometimes it captures the string the customer would enter it and save it in the variable, but if i use it in all cin, then it doesn't work but skips the entire thing

Any solutions per say you would see fit for this error?

When you switch to cin.getline you also run into the problem that it isn't appropriate for entering data to be stored as numbers, such as your phone number representation. But, that is more easily handled as a string anyway... I'm not sure why you're storing it in an int. Your choice variable, too, could be a string.

If you're mixing getline with extraction operations, then you're mixing formatted and unformatted input operations and those require care to use together since they don't handle whitespace in quite the same way. Easier to just use strings and getline.

I made a slight change to the entire code. I've implemented the suggested solutions in the code, but no luck.

If someone could help me debug the entire code to maybe come up with the best solution, would be a lot of help.

here's the link to the entire code: cpp.sh/26ioi or cpp.sh/2ihg5
