store (c) ; // use vector class library // declare arrays // put values into arrays // define vectors of 8 f l o a t s each // load array a into vector // load array b into vector // do operations on vectors // save result in array c Example 1.2 does the same as example...
One of the basic classes implemented by the Standard Template Library is the vector class. A vector is, essentially, a resizable array; the vector class allows random access via the [] operator, but adding an element anywhere but to the end of a vector causes some overhead as all of the...
The C++ Standard Library vector class is a class template for sequence containers. A vector stores elements of a given type in a linear arrangement, and allows fast random access to any element. A vector is the preferred container for a sequence when random-access performance is at a premium...

1) 绝大多数情况下，使用的是默认的 std::allocator 分配器，这时vector::vector(size_type n)就会有...
vector<string> svec(5); 编译器首先使用 string 默认构造函数创建一个临时值,然后使用复制构造函数将临时值复制到 svec 的每个元素。 (7)构造函数与数组元素 如果没有为类类型数组提供元素初始化式,则将用默认构造函数初始化每个元素。 如果使用常规的花括号括住的数组初始化列表来提供显式元素初始化式,则使用复...
