Resistance in parallel and series

Question

How do I calculate resistance in parallel and series using cpp

R1=2.5 and R4=4 in series
R2=6 and R3=2 in parallel

Answer 1

Amo Moses Dabanka do you know any C++ ? Just an introductory knowledge is enough. first one is a simple addition and second one is R2*R3/(R2+R3);

Answer 2

Thanks
