What do you precisely mean by "execution flow"?
Write a c++ code for a calculator with the following specifications:
(a)there are four arithmetic operations (+-*/) to be performed
(b)there are four control operations (e, u, d, s) to be managed such that:
(i) User enters 'e' to exit or any other key to continue with another expression.
(ii) User enters 'u' for up and 'd' for down to scroll through previous expressions the user has entered.
(iii) User enters 's' if s/he wishes to redo a previous calculation; in that case, the previously entered operation is executed.

I and II
III and IV
I and II have equivalent iterations and III and IV have equivalent iterations.
