bbb
举一反三
- 将当前目录下的abc文件复制到当前目录下,更改名称为bbb A: cp ./abc ./bbb B: cp abc /bbb C: cp/abc /bbb D: cp/abc ./bbb
- 以下连接字符串的代码正确的是（ ）。 A: $myVar3 = "aaaa" + "bbb"; B: $myVar3 = "aaaa" . "bbb"; C: $myVar3 = "aaaa" join "bbb"; D: $myVar3 = join("aaaa","bbb");
- 执行lis1 = [x*3 for x in "ABC"]后,lis1结果是( )。 A: ["AAA", "AAA", "AAA"] B: ["BBB", "BBB", "BBB"] C: ["CCC", "CCC", "CCC"] D: ["AAA", "BBB", "CCC"]
- bbb
- 若有chars[3][3]={"AAA","BBB","CCC"};说明语句，则与它等价的语句是（）。 A: char**s={"AAA","BBB","CCC"}; B: char*s[3]={"AAA","BBB","CCC"}; C: chars[][5]={"AAA","BBB","CCC"}; D: chars[][3]={"AAA","BBB","CCC"};
