The first line takes the value of variable "v1" and stores it to the
memory location to which "p1" points (dereferences pointer "p1");

The second line takes the address of variable "v1" (by invoking
"address of" operator) and assigns this address to pointer "p1" thus
making "p1" point to the variable "v1".
