Fixing Conditional Logic for Insurance Quote Calculation in C#

When programming, especially when you're new to a language, it’s easy to make small mistakes that can lead to bigger problems. In the case of managing conditions based on user input, such as whether someone smokes or not, incorrect logical operators can completely change the flow of your program.

In this post, we’ll discuss a common error in C# related to using the wrong comparison operators when checking user input, particularly in an insurance quote calculation program.

The Problem: Misusing Comparison Operators

Take a look at the following snippet of code:

What’s Wrong?

The issue arises from the following points:

The != operator checks if the input is not equal to the specified values. This means that if the user inputs any response other than “y”, “Y”, “yes”, or “Yes”, it would incorrectly trigger the first block that adds 75 to BaseQuote.

Similarly, for the second condition, if the input isn’t matching “n”, “N”, “no”, or “No”, it will not function as intended.

This results in the program adding 75 to the BaseQuote even if the user replied with "no".

The Solution: Correct Usage of Comparison Operators

To solve this, you need to change the comparison operators from != (not equal) to == (equal). Here’s the corrected code that implements this change:

Breakdown of the Changes

Condition for Adding: Now, the first if statement checks if SmokerStatus matches any of the values indicating the person does smoke. If it does, it adds 75 to the BaseQuote.

Condition for Subtracting: The second else if checks if SmokerStatus indicates the person does not smoke, subtracting 100 from the BaseQuote.

Conclusion

By correcting the logical operators in your conditions, you ensure that your code behaves correctly based on user input. Always remember to choose the right operator to avoid future errors, especially in branching logic where the right path needs to be taken based on user responses.

If you're new to programming, don’t hesitate to ask for help or research as mistakes help you learn. Keep coding, and good luck with your insurance program!
