go pointers
- Pointers in Go are variables that store the memory address of another variable.
- They are declared using the asterisk (*) followed by the data type of the stored value.
- To access the value pointed to by a pointer, the asterisk (*) operator is used.
- The "&" operator is used to get the memory address of a variable.
- Pointers can be used to pass variables by reference to functions, allowing the function to modify the original value.
- Go has a special type of pointer called a nil pointer, which points to no location in memory.
- Pointers in Go are used to create data structures like linked lists and trees.
