a. Write, compile, and execute a C++ program to calculate the resistance of a series circuit consisting of twelve 56-ohm, twenty 39-ohm, thirty-two 27-ohm, and twenty-seven 15-ohm resistors. The total resistance of a series circuit is the sum of all individual resistances. Your program should produce the following display (replacing the xxxx with the actual resistance value your program calculates): The total resistance, in ohms, is xxxx
b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to calculate the resistance of a series circuit consisting of seventeen 39-ohm resistors, nineteen 27-ohm resistors, and forty-two 15-ohm resistors.
