Here are the definitions for the member functions set_element and the constructor Pair with two arguments.

// Use iostream and cstdlib template void Pair::set_element(int position, T value) { if(position == 1) first = value; else if(position == 2) second = value; else { cout << "Error: Illegal pair position. "; exit(1); { }

template Pair::Pair(T first_value, T second_value) : first(first_value), second(second_value) { // empty body }

Important note: The class name before the scope resolution operator is Pair, not simply Pair.

Write the definitions for the member functions get_element for the class template Pair and the constructor Pair( ) with no argument. Add to the class a member function called display_pairs that displays the pairs. Then write a complete program that uses the class to read a pair of integers and a pair of strings and assign them to the appropriate objects, grades and names. Here is an example of an input pair:

first pairs: 87 90

second pairs: Tom Martha
