#pragma vector=PORT1_VECTOR表示中断函数是为    的中断服务的。

下列创建vector容器对象的方法中,错误的是( ) A: vector v(10); B: vector v(10, 1); C: vector v{10, 1}; D: vector v = (10, 1);

PORT1_VECTOR指明是P1口中断源。

配置交换机端口的Trunk模式正确的是() A: <;H3C>; int g1/0/1[H3C -GigabitEthernet1/0/1] port trunk permit vlan 10[H3C -GigabitEthernet1/0/1]port link-type trunk B: [H3C] int g1/0/1[H3C -GigabitEthernet1/0/1]port link-type trunk[H3C -GigabitEthernet1/0/1] port trunk permit vlan 10 C: [H3C -GigabitEthernet1/0/1] port link-type trunk permit vlan 10 D: [H3C] int g1/0/1[H3C -GigabitEthernet1/0/1] port trunk permit vlan 10[H3C -GigabitEthernet1/0/1]port link-type trunk

创建VLAN与端口加入VLAN的方法正确的是() A: <;H3C>; system-view[H3C]vlan 10[H3C-vlan10] port g 1/0/1 B: <;H3C>;vlan 10[H3C-vlan10] port g 1/0/1 C: <;H3C>; system-view[H3C] port g 1/0/1 D: <;H3C>; system-view<;H3C>;vlan 10<;H3C-vlan10>; port g 1/0/1

根据如下所示的命令，下列描述中正确的是（）。 [Huawei-GigabitEthernet0/0/1]port link-type access [Huawei-GigabitEthernet0/0/1]port default vlan 10 [Huawei-GigabitEthernet0/0/2]port link-type trunk [Huawei-GigabitEthernet0/0/2]port trunk allow-pass vlan 10

If F is a vector field, then divF is a vector field.

In the vector field, the vector line is such a curve where ( ) A: The tangent direction at each point on it is orthogonal to the direction of the vector field at that point. B: The tangent direction at each point on it is parallel to the direction of the vector field at that point. C: The value of each point on it is equal to the value of the vector field at that point. D: The vector line is the geometric curve of the vector field function.

The coordinates of a vector relative to a basis in a vector space is unique.

下面哪条语句创建了一个存有10个整数的vector对象？ A: std::vector<int> v(10); B: std::vector v; C: std::vector v[10]; D: std::vector<int> v[10]; E: std::vector(int) v;
