🧑💻Pointers are variables that store the memory address of other variables.
🔢Pointers can be used to modify the value of a variable by dereferencing them.
🖥️Different types of pointers include integer pointers, character pointers, and function pointers, among others.
🔀Pointer arithmetic can be performed by adding or subtracting from a pointer.
💡Void pointers can store the address of any data type and need to be typecasted before dereferencing.
What is the purpose of using pointers in programming?
—Pointers allow for efficient memory management and manipulation of data.
How do you declare a pointer in C?
—To declare a pointer in C, you use the '*' symbol before the pointer variable name.
What is pointer arithmetic used for?
—Pointer arithmetic is used for navigating through arrays and dynamically allocating memory.
What is the difference between null pointer and wild pointer?
—A null pointer points to no memory location, while a wild pointer points to an unpredictable or deallocated memory location.
Can a pointer point to itself?
—Yes, a pointer can point to its own memory address.
