Function rtsafe uses Doub f and Doub df for function value und derivative. Their declaration is just before the iteration loop. However, inside this loop, towards the end, Doub f and Doub df are declared again thus shadowing the first declaration.
This gives unpredictable results, since the initial values of f and df are needed inside the loop.
Just remove the keyword Doub from f and df inside the loop and everything is working fine.

Hello Comrade,
The suggestion is to be clarified vide the following,as it still finds bugs,though explicit action for the rtsafe method is declared and the x1,x2,xacc are also initialised
but on execution it has one error sayng that
funcd not defined in this scope though the same was removed purposely and explicity feature was included .
Thanking You
