试题 四(10 分 ) 阅读下列说明,回答问题1至问题3,将解答填入答题纸的对应栏内。 [说明] 逻辑覆盖是通过对程序逻辑结构的遍历实现程序的覆盖,是设计白盒测试用例的主要方法之一。以下代码由C 语言书写,请按要求回答问题。 void cal( int n ) { int g, s, b, q; if ( ( n > 1000 ) && ( n < 2000 ) ) { g = n % 10; s = n % 100 / 10; b = n / 100 % 10; q = n / 1000; if( ( q + g ) == ( s + b ) ) { printf("%-5d", n); } } printf("\n"); return; }
[问题 2](4 分) 请分析并给出分别满足100%DC(判定覆盖)和100%CC(条件覆盖)时所需的逻辑条件。
