go pointers

  1. Pointers in Go are variables that store the memory address of another variable.

  3. To access the value pointed to by a pointer, the asterisk (*) operator is used.
  4. The "&" operator is used to get the memory address of a variable.
  5. Pointers can be used to pass variables by reference to functions, allowing the function to modify the original value.
  6. Go has a special type of pointer called a nil pointer, which points to no location in memory.
  7. Pointers in Go are used to create data structures like linked lists and trees.
