What are some examples of data dependency issues?

Data dependency issues occur when the execution of one operation depends on the result of another. For example, if a variable is updated in one part of the code and then used in another without proper synchronization, it can lead to incorrect results.

Can you give me a specific coding example?

Sure! In a simple program, if you have a variable x that is assigned a value in one function and then used in another function without ensuring that the first function has completed, you might get unexpected results.

How can I avoid these issues in my code?

To avoid data dependency issues, you can use techniques like proper synchronization, avoiding global variables, and ensuring that functions are called in the correct order.

Are there tools that can help identify these issues?

Yes, there are static analysis tools and linters that can help identify potential data dependency issues in your code before runtime.
