First Flight #2: Puppy Raffle

Summary

To improve clarity and avoid potential confusion, it's advisable to change the return value of the getActivePlayerIndex function from 0 to -1 or use a more descriptive constant value when the player is not found in the array. This adjustment ensures that a valid index (0) in the array does not mislead users into thinking that the player was found.

Vulnerability Details

Returning 0 in the getActivePlayerIndex function may cause confusion, as it's a valid array index, potentially leading to misinterpretation by users. It's advisable to use a different return value, like -1, to clearly indicate the absence of the player and avoid such confusion.

Impact

Returning 0 in the getActivePlayerIndex function might mislead users into thinking that 0 corresponds to a valid index in the array. This could potentially lead to incorrect interpretations of the function's output and incorrect usage by developers.

Tools Used
