Based on working through each of these methods, discuss why the need for communication security protocols is significant. First, decode each of the ciphers. Second, discuss how communication security measures are built upon these principles. Third, discuss which existing communication security protocol you believe bears the greatest significance with regard to the level of protection that is offered. Finally, in responding to your peers’ posts, discuss whether or not you believe there are any communication security protocols that were not mentioned but are of a greater significance.

Consider the following code snippet: #ifndef cashregister_h#define cashregister_hconst double max_balance = 6000000.0; class cashregister{public: cashregister(); cashregister(double new_balance); void set_balance(double new_balance); double get_balance() const; private: double balance[12]; }; double get_monthly_balance(cashregister bk, int month); #endifwhich of the following is correct? a)the header file is correct as given.b)the definition of max_balance should be removed since header files should not contain constants.c)the definition of cashregister should be removed since header files should not contain class definitions.d)the body of the get_monthly_balance function should be added to the header file.

Write a method so that the main() code below can be replaced by the simpler code that calls method original main(): public class calcmiles { public static void main(string [] args) { double milesperhour; double minutestraveled; double hourstraveled; double milestraveled; milesprhour = scnr.nextdouble(); minutestraveled = scnr.nextdouble(); hourstraveled = minutestraveled / 60.0; milestraveled = hourstraveled * milesperhour; system.out.println("miles: " + milestraveled); } }

In cell b18, enter a formula to calculate the amount budgeted for meals. this amount is based on the daily meal allowance and the total travel days (# of nights+1).
