Depending on the value of the variable verbose, this prints out the iteration information. If verbose=0, then no information is printed, while if verbose>1, then after each iteration, the present values of x
and y
are output to std::cout along with the iteration number. If verbose>=2 then each iteration waits for a character before continuing.
