1. the process of creating workable systems in a very short period of time is called (a) rapid application development. (b) joint application design. (c) rapid outsourcing. (d) object-oriented development. 2. which of the following situations is most suited to rapid application development? (a) it is necessary to write most of the new code manually. (b) it is ok if the result is about 80 percent functional. (c) there is a large budget for the project. (d) the users are not available to participate in the development process. 3. which of the following is a benefit of prototyping? (a) if the prototype is well received by end users, redesign and documentation needs are minimal. (b) large quantities of data can be accommodated. (c) systems are likely to fulfill user requirements. (d) since users have been involved in the prototyping, managers can be confident that the system can handle large numbers of users. 4. you have started a software development firm, and your goal is to be as customer-focused as possible. which of the following system development methods is most appropriate to your organizational goal? (a) object-oriented development (b) extreme programming (c) rapid application development (d) prototyping 5. which of the following statements does not represent an advantage of object-oriented development (ood)? (a) code that is produced using ood is easy to reuse. (b) code that is produced using ood is easy to read. (c) code that is produced using ood is easy to secure. (d) code that is produced using ood is easy to modify. 6. which of the following is not true about testing in microsoft® windows xp? (a) more testing is preferable to less testing. (b) programmers perform tests by attempting to break the code they have written. (c) code is written for all of the features before testing commences. (d) acceptance tests verify whether customer requirements have been met. 7. a coffee shop is developing a new system for recording transactions. first, it asks the users what inputs and outputs are required of the system. then the shop develops an initial system that fulfills those requirements. then the users test the system, and adjustments are made to the system based on results of the test. this gets repeated until the system works. the refined system becomes the official system. which of the following development systems does this situation represent? (a) extreme programming (b) rapid application development (c) object-oriented development (d) prototyping 8. the specific term for expediting the delivery of software by breaking a task into smaller increments is? (a) object-based development. (b) rapid application development. (c) agile methods. (d) component-based development. 9. all mammals have fur. a dog is a mammal. therefore, a dog has fur. this set of statements is a representation of which object-oriented development (ood) concept? (a) object (b) encapsulation (c) polymorphism (d) inheritance 10. which of the following statements does not reflect a disadvantage of adopting object-oriented development ood? (a) the code is less accessible during the development phase than traditional code. (b) the code can only represent information as objects. (c) the code requires more monitoring than traditional code. (d) objects are dependent on each other.

1. package newton’s method for approximating square roots (case study 3.6) in a function named newton. this function expects the input number as an argument and returns the estimate of its square root. the script should also include a main function that allows the user to compute square roots of inputs until she presses the enter/return key. 2. convert newton’s method for approximating square roots in project 1 to a recursive function named newton. (hint: the estimate of the square root should be passed as a second argument to the function.) 3. elena complains that the recursive newton function in project 2 includes an extra argument for the estimate. the function’s users should not have to provide this value, which is always the same, when they call this function. modify the definition of the function so that it uses a keyword parameter with the appropriate default value for this argument, and call the function without a second argument to demonstrate that it solves this problem. 4. restructure newton’s method (case study 3.6) by decomposing it into three cooperating functions. the newton function can use either the recursive strategy of project 1 or the iterative strategy of case study 3.6. the task of testing for the limit is assigned to a function named limitreached, whereas the task of computing a new approximation is assigned to a function named improveestimate. each function expects the relevant arguments and returns an appropriate value. 5. a list is sorted in ascending order if it is empty or each item except the last one is less than or equal to its successor. define a predicate issorted that expects a list as an argument and returns true if the list is sorted, or returns false otherwise. (hint: for a list of length 2 or greater, loop through the list and compare pairs of items, from left to right, and return false if the first item in a pair is greater.)
