What would happen if a variable is not initialized before use in Karel's program?

In Karel's programming environment, if a variable is not initialized before use, it can lead to an error scenario where the program exhibits unexpected behavior. This situation arises because the program tries to reference a variable that does not have a defined value, which can disrupt the flow of execution.

When a variable is expected to hold a specific value but instead lacks initialization, the program may not know how to handle operations involving that variable. Consequently, this may result in runtime errors or undefined behavior, causing potential issues during the execution of Karel’s tasks.

Initialization is a crucial step in programming, as it provides variables with a defined state, and omitting this step can lead to confusion and errors that affect the reliability and predictability of the program.
