##Write a program that asks the user how many sets of 2 numbers they have (n).
 ##input n sets of 2 numbers.
 ##Output in how many sets the numbers were equal
 ## Implement a for loop with an iterator. Also, since there apparently isn't a "is exactly equal," I will need to implement a double condition of 
## if not greater than, if not less than
 ## t0 = number of iterations the user wants, t1 = our internal increment counter, t2 = first number user enters
## t3 = second number user enters, t4 = the count of how many equal t2/t3 pairs there are
