hello, please i make a code that i want it to work as follows:
the user input 3 value and after an inspection(that i am not put it now, i want to try it now so i make the condition, if k%2==0)the input is be either spoof or valed,at the begining the state is alert, then i compute the (th)it is a threshold value, so if it is spoof and the th is less than T1 the o/p is accept, and still that(when the user enter other 3 values) untill the th be larger than T1 and then it is switch to the action state and the o/p is (if it is spoof the o/p is drop and if it is not spoof the o/p is forword)and still that (when the user enter other 3 values) until the th is less than T2
so i do my best and write that code but it's o/p is not like that i want, please can u do any help for me,
thank u very much in advance
