1、为“遍历元素的loop结束时机”提供一个简单的判断依据。只要尚未到达end(),loop就可以继续进行。 2、不必对空区间(empty range)采取特殊处理收发。空区间的begin()就等于end()。 任何容器都定义有两种迭代器类型: 1.container::iterator 以“读/写”模式遍历元素。 2. container::const_iterator以“只读”模式...
for循环有一个隐藏的陷阱,如果不注意可能会出现严重的内存错误,将for-each原理抽象成下列公式 attr(optional) for ( range_declaration : range_expression ) loop_statement 将其解释为 { auto && __range = range_expression; for (auto __begin = begin_expr, __end = end_expr; __begin != __end...
That's it! With these five functions, you can have a data structure that works with a range-based for loop. Because the begin and end methods can be non-member functions ( begin( container ) instead of container.begin() ), you can even adapt existing data structures that don't ...
} Declaring elem as a reference is important because otherwise the statements in the body of the for loop act on a local copy of the elements in the vector. To avoid calling the copy constructor and the destructor for each element, you should usually declare the current element to be a co...
Instead, use vstest.console.exe. See VSTest.Console.exe command-line options. mutable keyword The mutable storage class specifier is no longer allowed in places where previously it compiled without error. Now, the compiler gives error C2071 (illegal storage class). According to the standard, ...
For an ACL, when the rule command is used to configure a filtering rule, the filtering rule is effective only with the source address range that is specified by the source parameter and with the time period that is specified by the time-range parameter. Creating an ACL before it is referen...
color scale:A specific range of colors that is used to give additional meaning to data by assigning certain values to colors in the spectrum. color scheme:A table of color values that enables colors to be referenced by an index value in the table instead of a color value. See alsocolor ...

A time range is created. By default, no time range is configured on a device. You can specify multiple time ranges for time-name. The device obtains the intersection of the configured periodic or absolute time ranges. To delete a time range, see Deleting a Time ...
