The 20h is the offset from the top of the stack to the address where this variable’s storage is located. If we were to look at a stack of this application it would like the diagram below. WebPointers can reference other pointers, and in such cases, multiple applications of the dereference operator are needed. Similarly, the Java dot operator can be used in compositions forming quite sophisticated statements that require substantial dereferencing of pointers behind the scenes during evaluation.
