Common Mistakes to Avoid When Working with Input and Output in Console Apps

1. Mismatched Data Types:

   • Many beginners try to read input as one type (like a word or sentence) but then try to use it as another type (like a number).
   • This can cause errors when the program runs.
   • Solution: Always check and change the data type when needed.

2. Ignoring Input Validation:

   • Sometimes, users might type in information that the program doesn’t expect.
   • This can cause problems, like making the program crash.
   • Solution: Set up rules to make sure the input is what you want.

3. Using Hard-Coded Values:

   • When you write fixed values directly into the code, it can make things harder to change later on.
   • If you need to update something, it can lead to mistakes.
   • Solution: Use variables and constants so that your program can adjust easily.

4. Neglecting Edge Cases:

   • If you don’t think about extreme or unusual inputs, the program might behave in ways you don’t expect.
   • Solution: Test your program with all kinds of possible inputs to make sure it works well.
