Which phase of the software life-cycle is usually the most expensive?

What will happen if a function is executed and the precondition for the function is not met?

What does a run-time analysis usually count?

What is the common pattern of class definitions that is used in Chapter 2?

Here is a small function definition: void f(int i, int &k) { i = 1; k = 2; } Suppose that a main program has two integer variables x and y, which are given the value 0. Then the main program calls f(x,y); What are the values of x and y after the function f finishes?

When we pretend that we do not know how a function is implemented, we are using a form of information hiding called ___________________________.

Suppose you write a program that accepts as input any integer in the range –20 through 20, and outputs the number of digits in the input integer. What boundary values should you use as test inputs?

What are two rules, which are suggested in the textbook, for fully exercising code?

What statement about "assert" statement in a C++ program is the most accurate?

What boundary values should we use as test inputs for the day variable in the function date_check of ch1 around page 15 of the textbook.

What is the easiest way to turn off all assertion checking in a program?

Which of the three forms

a. using namespace main_savitch_2A;

b. using main_savitch_2A::throttle;

c. main_savitch_2A::throttle apollo;

should be used when part of anamespace needs to be used within an actual header file?

What are the common patterns for Classes?

a. Public member functions permit programmers to modify and examine objects of the new class.

b. Private member functions permit programmers to modify and examine objects of the new class

.c. Use the keyword const (after the function’s parameter list) when a member function examines data without making modifications.

d. Private member variables of the class store the information about the status of an object of the class.

Which statement of the following is the most appropriate?

A ___________________ is declared by writing the type name followed by the parameter name. With the parameter, the argument provides the initial value for the formal parameter. The parameter is implemented as a local variable of the function, so that any changes made to the parameter in the body of the function will leave the argument unaltered.

A ________________________ is declared by writing the type name followed by the character & and the parameter name. With the parameter, any use of that within the body of the function will access the argument from the calling program. Changes made to the formal parameter in the body of the function will alter the argument.

What is an object in C++?

The following is part of a C++ programming.void throttle::shut_off( )// Precondition: None.// Postcondition: The throttle has been turned off.{ position = 0;}We use the term _________________ to describe a full function definition such as above.

What would be one of the common place where the scope resolution operator throttle:: is used.(Ch2 around P42)?

Why is it important to test boundary values when testing programs?

Which of these is used to stop the program execution when a precondition is not met.

What term is used to describe an O(n) algorithm.

Here is the start of a class declaration: class foo { public: void x(foo f); void y(const foo f); void z(foo f) const; ... Which of the three member functions can alter the PRIVATE member variables of the foo object that activates the function?

Consider this class definition: class quiz { public: quiz( ); int f( ); int g( ) const; private: double score; }; Which functions can carry out an assignment score=1.0; to the private member variable score?

What statement about "assert(c >= MINIMUM_CELSIUS);" statement in a C++ program is the most accurate?

A variable is a declared constant, which means ___________________________________________.

Which of the following belong to the Phases of Software Development?a. Specification of the taskb. Design of a solutionc. Implementation (coding) of the solutiond. Analysis of the solutione. Testing and debuggingf. Maintenance and evolution of the systemg. Obsolescence

Which statement of the following is the most appropriate?

What statement about the order of an algorithm is the most accurate?

Counting the maximum number of operations is called the ______________________________.

One of the libraries is the facility, which contains a function with this prototype:double sqrt(double x);The function returns the square root of x. Which would be a reasonable precondition and postcondition for this function?

Where would a programmer read to learn how to use a new class?

Which statement of the following is the most appropriate?

Please refer to Ch2 throttle class, which of these function calls could change the value of a point p:cout << rotations_needed(p);rotate_to_upper_right(p);

Which statement of the following is the most appropriate?

When should a member of a class be declared public?

A _______________________________ may examine the status of an object, but changing the object is forbidden.

Suppose a function has a parameter named x, and the body of the function changes the value of x. If we do not want the change affect to the original x, what type of parameter x should we use?

A modification member function can change the value of an _________________________.
