The program, when ran, will let the user roll a pair of dice n-times (i.e. generate a number between 1 and 6), where n is a positive integer entered by a user. The program then outputs the pair of numbers rolled by the dice, as well as the sum of the numbers rolled by each pair of dice. The pairs of numbers are stored in a 2-dimensional array, and the sum of each pair are stored in a single-dimensional array. Debug the program.
