What are some common issues with user variables in programming?
Common issues include variable scope, uninitialized variables, and type mismatches.
Can you explain variable scope?
Variable scope refers to the accessibility of a variable in different parts of the code. It can be local or global.
What happens if I use an uninitialized variable?
Using an uninitialized variable can lead to unpredictable behavior or runtime errors, as it may contain garbage values.
How can I avoid type mismatches?
To avoid type mismatches, always declare variable types explicitly and use type-checking tools.
