a) Suppose you are working with an array of size 10. It contains all the numbers from 1 to 10 exactly once in a random order. But accidentally, one of the numbers in the array got replaced by a zero (0). Write a C/C++ programme using functions, to restore the lost number.

b) What is polymorphism in the context of an object-oriented paradigm? Explain the method of overloading and method of overriding with suitable examples.
