Fix Your C++ Program Input Issue: Stop Asking for More Data Than Necessary!

As a beginner in programming with C++, it's common to encounter confusing behaviors when getting input from users. If you're facing an issue where your program keeps asking for more input than necessary during the account creation process, you’re not alone. This guide will zero in on this problem—identifying the root cause—and providing a straightforward solution to cleanly handle user input. Let’s get right into it!

The Problem: Repeated User Input

In your program, when users are prompted to select a role (either Tier I, Tier II, or Tier III) for account creation, they only need to choose an integer corresponding to their desired role. The initial idea was to collect this input once and store the value appropriately. However, the unexpected behavior arises during the role selection process, leading to confusion and errors.

How it Happens:

The program prompts the user for their role by entering an integer (1 to 3).

After inputting their choice and hitting enter, the program erroneously asks for the role again.

As a result, the user must input two pieces of data when only one was intended, leading to interference in the account creation process.

Here’s an excerpt from the section of the code that causes the confusion:

The Solution: Remove Redundant Input

To solve this issue, all you need to do is remove that extra input line where you are asking for the role again similar to how you did for the username and password. The corrected section of the createAccount() function would look like this:

Summary of Changes:

Removed the line cin >> user.role; as it redundantly asked for input a second time.

Conclusion

That’s all there is to it! By removing a single input line, your C++ program should now prompt users as expected without additional requests for their role. This adjustment leads to a smoother experience when creating an account, allowing users to proceed to the next steps seamlessly.
