在Web应用程序中，编写了公共的处理页面名为manage.jsp，该页面包含在Web根目录下名为util的文件夹中，那么在Web根目录下的其他页面上引用该页面的代码正确的是（ ）。 A: <% include file="util/manage.jsp"%> B: <%@ include file="util/manage.jsp"%> C: <%! include file="util/manage.jsp"%> D: <include file="util/manage.jsp">

读代码： 1.packagefoo; 2.importjava.util.Vector; 3.privateclassMyVectorextendsVector{ 4.inti=1; 5.publicMyVector(){ 6.i=2; 7.} 8.} 9.publicclassMyNewVectorextendsMyVector{ 10.publicMyNewVector(){ 11.i=4; 12.} 13.publicstaticvoidmain(Stringargs[]){ 14.MyVectorv=newMyNewVector(); 15.} 16.} 结果是：

阅读下面的代码，下面的叙述哪些是正确的() A: 行2不会为变量myVect分配内存空间 B: 行2为Vector对象的引用分配内存空间 C: 行2创建了一个Vector类的对象 D: 行3创建了一个Vector类的对象

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.

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);

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

定义STL容器类vector的对象v如下，则下列操作有误的是（）。vector<;int>; v(10); A: v.push_front(1) B: v[2] = 2 C: v.back() = 10 D: cout <;<; v.size()

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;

Any subset of a vector space V which contains the zero vector is a subspace of V.
