Question: 1 / 400

What will be the result of calling a function with an uninitialized pointer as an argument?

It will work as expected.

Undefined behavior.

When a function is called with an uninitialized pointer as an argument, the result is undefined behavior. This occurs because an uninitialized pointer does not point to a valid memory location, leading to unpredictable outcomes when the function attempts to dereference or manipulate the pointer.

In programming languages such as C and C++, a pointer needs to point to a valid memory address before it can be safely used. If you pass an uninitialized pointer, the function may try to read from or write to an arbitrary memory location, which could crash the program, cause data corruption, or lead to security vulnerabilities. Therefore, understanding the significance of proper pointer initialization is crucial for writing robust and error-free code.
