(a) Mention two basic differences between 'call by value' and 'call by Reference'. Write a program in c/c++ Programming language to swap two integer values using 'call by Reference'.

(b) Consider the following code snippet in a C like Programming language-

int a = 5, b = 18, c = 27;
a = b++ +++c;
b = a++ C--;
C=a++ + b--;

What will be the output of a, b, and c after execution of the above statements? Explain your answer.

(c) What is polymorphism? Write a Java program to demonstrate the compile time and run time polymorphisms.

(d) What is Just In Time (JIT) compiler? How does it support machine independent programming?
