A: ../files/images/ch_cook1.gif
B: ./file/ch_cook1.gif
C: /pic/folder/images/ch_cook1.gif
D: c：/pic/images/ch_cook1.gif
举一反三
- 下面哪一个不是相对路径的表示方式?()。 A: ../files/images/ch_cookl.gif B: ./file/ch_cookl.gif C: /pic/folder/images/h_cookl.gif D: c:/pic/images/ch_cookl.gif
- 有以下程序 #include main( ) { char ch[] = "abc"; ch[0] ^= ch[0]; ch[1] |= ch[1]; ch[2] &= ch[2]; printf("%d%c%c\n",ch[0],ch[1],ch[2]); } 程序运行后的输出结果是
- ch是字符型变量,下面不正确的赋值语句是()。 A: ch=‘a+b’; B: ch=‘’; C: ch=‘1’+‘2’ D: ch=60+5
- 下面程序的输出结果是（ ）Private Sub proc(ch As String) s = "" For k = Len(ch) To 1 Step -1 s = s & Mid(ch, k, 1) Next k ch = sEnd SubPrivate Sub Command1_Click() ch$ = "ABCDEF" proc ch Print ch End Sub A: ABCDEF B: A C: FEDCBA D: F
- She's ______ as her mother. A: as a good cook B: a good cook as C: as good a cook D: a as good cook

判断ch是数字字符的C语言表达式是( ) 。 A: '0' <= ch <= '9' B: ch >= '0' && ch <= '9' C: ch >= '1' && ch <= '10' D: ! (ch < '0' || ch > '9') E: ch >= '0' || ch <= '9'

下面的代码用于输出字符数组ch中每个字符出现的次数， 应填入(1)处的代码是 char[] ch = { 'a', 'c', 'a', 'b', 'c', 'b' }; HashMapmap = new HashMap(); for (int i = 0; i < ch.length; i++) { if(___(1)____){ map.put(ch[i], map.get(ch[i]) + 1); } else{ map.put(ch[i], 1); } } System.out.println(map);[/i][/i][/i] A: map.contains(ch[i]) B: map.containsValue(ch[i]) C: map.containsKey(ch[i]) D: map.indexOf(ch[i])
