ch. 9 python programming
false
a developer should use either top-down or spiral design , but not both (T/F)
d
a graphical view of the dependencies among components of a design is called a(n) a- flowchart b- prototype c- interface d- structure chart
false
a simplified version of a program is called a simulation (T/F)
a
a simulation that uses probabilistic events is called a -Monte Carlo b- pseudo-random c- Monty Python d- chaotic
false
a top-down design is best implemented from the top down (T/F)
false
the python random funtion returns a pseudo-random int (T/F)
true
top-down design is also called stepwise refinement (T/F)
true
unit-testing is the process of trying out a component of a larger program in isolation (T/F)
c
which expression is true approximately 66% of the time? a- random() >= 66 b- random() < 66 c- random() < 0.66 d- random() >= 0.66
c
which of the following is not a step in pure top-down design? a- repeat the process on smaller problems b- detail the algorithm in terms of its interfaces with smaller problems c- construct a simplified prototype of the system d- express the algorithm in terms of smaller problems
c
how is a percent sign indicated in a string-formatting template? a- % b- \% c- %% d- \%%
false
computers can generate truly random numbers (T/F)
a
in the racquetball simulation, what data type is returned by the gameOver function? a- bool b- int c- string d- float
true
in top down design, the main algorithm is written in terms of functions that dont yet exist(T/F)
c
in top-down design, the subcomponents of the design are a- objects b- loops c- functions d- programs
false
reading design books alone will make you a great designer (T/F)
a
the arrows ina module hierarchy chart depict a- information flow b- control flow c- sticky-note attachment d- one-way streets
b
the easiest place in a system structure to start unit-testing is a- the top b- the bottom c- the middle d- the main function
b
the initial version of a system used in spiral development is called a- starter kit b- prototype c- mock-up d- beta-version
true
the main function is at the top of a functional structure chart (T/F)
