A: struct{ int red; int green; int blue;} cor;
B: struct color cor{ int red; int green; int blue;};
C: struct color{ int red; int green; int blue;} cor;
D: typedef struct{ int red;int green;int blue;}COLOR;COLOR cor;
举一反三
- 以下选项中不能正确把 cl 定义成结构体变量的是 ______ 。 1 ． typedefstruct {intred; int green; int blue; } COLOR; COLOR cl; 2 ． structcolor cl { int red; int green; int blue; }; 3 ． structcolor { int red; int green; int blue; }cl; 4 ． struct {int red; int green; intblue; }c1;
- 阅读下面的程序， 请写出程序的输出结果 。 #include<iostream> using namespace std; int main () { enum Color {Red,Green,Blue}; Color color; color=Red; cout<<color<<","; color=Green; cout<<color<<","; color=Blue; cout<<color<<","; cout<<Red+Green+Blue<<endl; return 0; }
- 下面对枚举变量的定义中，正确的是( )。 A: enum color {red, blue, grenn} a, b; B: enum color={red, blue, green} a,b; C: enum color={"red", "blue", "green"} a, b; D: enum color {red, blue, green} a, b;
- 大千世界，五彩缤纷，颜色何止千万。除了Color类自带的已知颜色，还可以构造其他任何特殊的颜色。最常用的构造方式如下：Color c = Color.FromArgb(int alpha, int red, int green, int blue);其中，四个参数alpha、red、green和blue分别表示颜色透明度、红色分量、绿色分量和蓝色分量。它们的取值范围是_________。 A: 0 ~ 127 B: 0 ~ 255 C: 0 ~ 65535 D: 0 ~ 2147483647
- 以下结构体定义错误的是 A: struct ord {int x; int y} struct ord a; B: struct ord {int x; int y} ; struct ord a; C: struct ord {int x; int y} a; D: struct {int x; int y} a;
