Using the following grammar show a parse tree and a leftmost derivation for each of the following statements. (a and d) «assign>Explanation / Answer
P2.
P3.
Simply put aliasing is simply giving another identity for the same task.
Lets understand this with an example
a pointer is a value that represents a memory address sometimes 2 pointers can represent the same memory address thats what aliasing is
int * p;
*p = 5;
int * alias;
alias = p;
the variable alias is an alias of p and *alias is equal to 5 if you change *alias then *p changes along with it
P4.
High-level abstract isomorphic copies
Ex: Java, C
