Programming in C:
Write a program that
ask the user if the resistors are in series or parallel
read in the number of resistors
read in the resistance of the individual resistors by having the user enter the first three colors of the 4 bands on the resistor
calculate the total resistance of the circuit
print out the result
Also: format the output so it's more appealing (not so many 0's and uses appropriate suffixes K,M,G, etc) and handle invalid gracefully, if expecting a number and user gives a letter, or expecting a letter and get a number, or get wrong number of inputs, etc.
