单选题A typical (11) language contains an applicative sub-language which approximates the mathematical abstractions of "timeless" functions applied to "spaceless' values, where the actual operation sequences and use of storage space during expression evaluation are organized behind the (12) . In this setting, values are data structures of low volume, typically a few computer words or less, which means that an illusion of spacelessness can be realized by having (13) results during expression evaluation stored at the discretion of the language implementation, and effecting parameter (14) and (15) operations through value copying.
单选题给定C语言程序如下： int foo(int x，int y，int d) if(x!=0) if(y==0)d=d/x； else d=d/(x*y)； else if(y==0)d=0； else d=d/y； return d； 当用路径覆盖法进行测试时，至少需要设计______个测试用例。 A．3 B．4 C．5 D．8
单选题The purpose of the requirements definition phase is to produce a clear, complete, consistent, and testable (46) of the technical requirements for the software product. During the requirements definition phase, the requirements definition team uses an iterative process to expand a broad statement of the system requirements into a complete and detailed specification of each function that the software must perform and each (47) that it must meet. The starting point is usually a set of high-level requirements from the (48) that describe the project or problem. In either case, the requirements definition team formulates an overall concept for the system and then defines (49) showing how the system will be operated, publishes the system and operations concept document, and conducts a system concept review (SCR). Following the SCR, the team derives (50) requirements for the system from the high-level requirements and the system and operations concept. Using structured or object-oriented analysis the team specifies the software functions and algorithms needed to satisfy each detailed requirement.

单选题下列关于一个类的静态成员的描述中，不正确的是 (5) 。
单选题若循环队列以数组Q[O..m-1]作为其存储结构，变量rear表示循环队列中队尾元素的实际位置，其移动按rear=(rear+1) mod m进行，变量length表示当前循环队列中的元素个数，则循环队列的队首元素的实际位置是 (2) 。 A．rear-length B．(rear-length+m) mod m C．(1+rear+m-length) mod m D．m-length
单选题软件能力成熟度模型(CMM)的第4级(已定量管理级)的核心是______。
单选题Traditional structured analysis techniques focus upon the flow of (36) within a system. Object-oriented analysis emphasizes the building of real-world models. It examines requirements from the perspective of the classes and objects found in the vocabulary of the (37) domain. Traditional system design method emphasizes the proper and effective structure of a complex system. Object-oriented design method encompasses the process of object-oriented decomposition and a (38) for depicting both logical and physical as well as static and dynamic models of the system under design. Object-oriented programming is a method of implementation in which programs are organized as cooperative collections of objects, each of which represents an (39) of some class, and whose classes are all members of a hierarchy of classes united via (40) relationships.
