What are some common mistakes people make with variables in programming?

Some common mistakes include using uninitialized variables, incorrect data types, and scope issues.

Can you explain what you mean by uninitialized variables?

Sure! An uninitialized variable is one that has been declared but not assigned a value, leading to unpredictable behavior.

What about data types? How can they cause issues?

Using the wrong data type can lead to errors, like trying to perform arithmetic on a string instead of a number.

How can I avoid these mistakes?

You can avoid these mistakes by initializing your variables, using type checks, and understanding variable scope.
