Uninitialized pointer is a pointer variable that does not point to a valid memory location. When you attempt to dereference an uninitialized pointer, it can lead to unpredictable behavior, including crashes, data corruption, and security vulnerabilities.

Common Causes of Uninitialized Pointers:

• Missing Initialization: Failure to initialize a pointer variable before using it.
• Incorrect Memory Allocation: Allocating memory for a pointer but forgetting to assign it a valid address.
• Function Calls: Passing uninitialized pointers as arguments to functions.
• Return Values: Returning uninitialized pointers from functions.
