### 6.1.2测试与作业 ###

> 1单选(2分)关于模块的扇入扇出，以下说法正确的是\_\_\_\_\_\_\_  
> A.扇入表示有多少个上层模块直接或间接调用它  
> B.模块扇入高时应当重新分解，以消除控制耦合的情况  
> C.一个模块的扇出太多，说明该模块过分复杂，缺少中间层2.00/2.00  
> D.一个模块的扇入太多，说明该模块过分复杂，缺少中间层  
> 正确答案：C

> 2单选(2分)划分模块时，一个模块的\_\_\_\_\_\_  
> A.作用范围应在其控制范围内2.00/2.00  
> B.控制范围应在其作用范围内  
> C.作用范围与控制范围互不包含  
> D.作用范围与控制范围不受任何限制  
> 正确答案：A

> 3单选(2分)在对初始的MSD精化过程中，将多个模块公用的子功能独立出来，形成一个新的模块，这利用了哪一条启发式规则？  
> A.改进软件结构，提高模块独立性2.00/2.00  
> B.模块规模适中，每页60行语句  
> C.模块的作用域力争在控制域之内  
> D.降低模块接口的复杂性  
> 正确答案：A

> 4多选(2分)以下说法错误的是\_\_\_\_\_\_  
> A.启发式规则是人们从长期的软件开发实践中总结出来的规则，在设计中应当普遍遵循0.67/2.00  
> B.扇入扇出应当适中，尽量满足7+2原则0.67/2.00  
> C.好的设计控制域应当包含作用域  
> D.为了降低模块接口的复杂性，应当将多个同类型的参数合并为一个数组进行传递0.67/2.00
