a) Suppose that I have template class Pair is declared as following template

class Pair

{

public:

Pair();

Pair(T first_value, T second_value); void set_element(int position, T value);

// if the position is 1, set the first value in pair to be value;

// otherwise, set the second value in pair to be value;

// more functions private:

T _first_value; // the first value in pair

T _second_value; // the second value in pair

};

Implement the set_element member function

b) Write a trivial exception class named InsufficientFund.
