其中包括push()、pop()、shift()、unshift(),等等。Vector 对象的属性和方法与 Array 的属性和方法类似(大多数情况下完全相同)。对于大多数需要使用所含的所有元素都具有同一数据类型的 Array 的情况,Vector 实例都更为可取。不过,Vector 实例是密集数组,这意味着它必须在每个索引中具有一个值(或null)。Array ...
在上面的示例中,addData函数用于向data中添加数据,getDataSize函数返回data的大小,getDataAtIndex函数返回data中指定索引位置的值。 在使用该类的代码中,可以创建一个该类的对象,并使用公有成员函数来访问和修改私有的std::vector成员变量。 代码语言:txt
