Hi Palani,

I think void * will act as a generic pointer.

A "generic pointer" is not a specific term in programming C/C++ although it may, perhaps, be represented by a void *.

A void * is a pointer to a memory location without actually specifying what data that location stores.

When a variable is declared as being a pointer to type void it is known as a generic pointer. Since you cannot have a variable of type void, the pointer will not point to any data and therefore cannot be dereferenced. It is still a pointer though, to use it you just have to cast it to another kind of pointer first. Hence the term Generic pointer.
