What does dereferencing a pointer mean in C C++? When you want to access the data value in the memory that the pointer points to - the contents of the address with that numerical index - then you dereference the pointer
Dereference Pointer in C - GeeksforGeeks When we dereference a pointer, we deal with the actual data stored in the memory location it points to When we write *ptr, the compiler looks at the address stored in the pointer, goes to that memory location, and accesses or changes the actual data stored there — not a copy
