exercises review questions true/false computers can generate truly random numbers the python random function returns pseudo random int top-down design is also called stepwise refinement in top-down designthe main algorithm is written in terms of functions that don' yet exist the main function is at the top of functional structure chart top-down design is best implemented from the top down unit-testing is the process of trying out component of larger program in isolation developer should use either top-down or spiral designbut not both read design books alone will make you great designer simplified version of program is called simulation multiple choice which expression is true approximately of the timearandom(> crandom( brandom( drandom(> which of the following is not step in pure top-down designarepeat the process on smaller problems bdetail the algorithm in terms of its interfaces with smaller problems cconstruct simplified prototype of the system dexpress the algorithm in terms of smaller problems graphical view of the dependencies among components of design is called (naflowchart bprototype cinterface dstructure chart the arrows in module hierarchy chart depict ainformation flow bcontrol flow csticky-note attachment done-way streets in top-down designthe subcomponents of the design are aobjects bloops cfunctions dprograms simulation that uses probabilistic events is called amonte carlo bpseudo random cmonty python dchaotic
