What does the address operator '&' do in C programming?

• Gets the address of a variable

• Decrements a pointer

• Increments a pointer

• Assigns a value to a pointer

Why is it a good practice to assign NULL to a pointer variable in C programming?

• To avoid errors when accessing memory at address 0

• To confuse other programmers

• To increase memory usage

• To speed up program execution

What does incrementing a pointer in C programming do?

• Moves the pointer to the previous location
