Programming languages like C and C++ make use of pointers whereas the JAVA2 language is free of
pointers. A pointer is a variable that holds the memory address of another variable. It allows us to do
an indirect manipulation of that variable because it holds the address of that variable where it has
been stored in memory. Pointers have many applications and if used with care they can improve the
efficiency of our programs. Let us explore this and other concepts in this section.
