The predictor-corrector method is a combination of ______________(a) m

1.	The predictor-corrector method is a combination of ______________(a) midpoint and trapezoidal rules(b) backward Euler method and Trapezoidal rule(c) implicit and explicit methods(d) forward and backward Euler methodsI have been asked this question in a job interview.I would like to ask this question from Transient Flows topic in section Transient Flows of Computational Fluid Dynamics
Answer» The correct option is (c) implicit and explicit methods Easiest explanation: Explicit methods are very EASY to PROGRAM and they need LESS computational cost. But they are not STABLE. The implicit methods are unconditionally stable but more expensive and ITERATIVE. So, the positives of both of these methods are combined by the predictor-corrector method.
