15.7 CIST2362 Lab: Pairs (class templates)

Complete template class Pair by defining the following methods:

void Input()

Read two values from input and initialize the data members with the values in the order in which they appear

void Output()

Output the Pair in the format "[firstVal, secondVal]"

char CompareWith(Pair* otherPair)

Return the character '<', '=', or '>' according to whether the Pair is less than, equal to, or greater than otherPair

Precedence of comparisons is firstVal then secondVal

char ShowComparison(Pair* otherPair)

Compare with otherPair by calling CompareWith()

Output the two Pairs separated by the character returned by CompareWith(). Hint: Output each Pair using Output()

Note: For each type main() calls Input() twice to create two Pairs of that type.

Ex: If the input for two Integer Pairs is:

4 6 3 5 

the first Pair is [4, 6], and the second Pair is [3, 5].

Ex: If the input of the program is:

4 6 3 5 4.3 2.1 4.3 2.1 one two three four 

the output is:

[4, 6] > [3, 5] [4.3, 2.1] = [4.3, 2.1] [one, two] < [three, four]
