下列字符串函数的案例中,错误的是_______。 A: Right("Tongji",2)="ji" B: StrDup(4,"T")="TTTT" C: Left("Tongji",2)="To" D: ‍Mid("Tongji",2,2)="ng"

int x = 3,y = 4;以下哪条输出语句正确？ A: Console.WriteLine("x={x},y={y}", x,y); B: Console.WriteLine("x={x},y={y}"); C: Console.WriteLine("x={0},y={1}", x,y); D: Console.WriteLine("x={1},y={2}", x,y);

以下哪个选项是正确的json数据格式： A: { "id": 2, "userName": admin, "passWord": 12345, "email": admin@qq.com} B: { id: 2, userName: "admin", passWord: "12345", email: "admin@qq.com"} C: { "id": 2, "userName": "admin", "passWord": "12345", "email": "admin@qq.com",} D: { "id": 2, "userName": "admin", "passWord": "12345", "email": "admin@qq.com"}

若有以下定义: float x;int a,b; 则正确的switch 语句是( )。 A: switch(x) { case 1.0:printf("* "); case 2.0:printf("** "); } B: switch(x){ case 1,2:printf("* "); case 3:printf("** "); } C: switch (a+b) { case 1:printf(" "); case 1+2:printf("** "); } D: switch (a+b);{ case 1:printf(."* "); case 2:printf("** "); }
