4.) You've been asked to write a C++ program to calculate the total resistance of a series circuit. In this circuit, the total resistance is the sum of all individual resistance values. The circuit cosists of a number of 56-ohm, 33-ohm, and 15-ohm resistors. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. The number of 56-ohm resistors is m, the number of 33-ohm resistors is n, and the number of 15-ohm resistors is p. Test the formula written for Exercise 17, n = 24, and p = 12. d. te using the following sample data: m =
