Hi Santhosh, To remember it easily, just consider this.
We know polymorphism means, existing in more than one form. Consider '+' symbol. We can use this symbol to add two number, say c = a+b Or concatenate two string, say myName = "Karthik " + "Mohan" We as a human can interpret this. But how does a compiler understand that it need to add the first one and Concatenate the second one? This is by runtime polymorphism. Based on the two operands, the compiler decides whether it should add of concatenate. And reg extern, when a variable is declared extern, it can be accessed by any member of the project. We can call Extern as, universally global !
