Use the range-basedfor statement to construct loops that must execute through a "range", which is defined as anything that you can iterate through—for example,std::vector, or any other STL sequence whose range is defined by abegin() andend(). The name that is declared in thefor-range-...
在C++编程中,遇到错误信息 "range-based 'for' loops are not allowed in c++98 mode" 通常意味着你正在尝试在C++98标准模式下使用基于范围的for循环,但这一特性在C++98中并不支持。基于范围的for循环是C++11及更高版本引入的新特性,用于简化容器或数组的遍历。 问题解释 错误信息:"range-based 'for' loops ...
C++: Range-Based For Loops23 June 2017 by Phillip Johnston • Last updated 15 December 2021 One of the more frequently used C++ constructs I use is the range-based for loop. The range-based forloop format was introduced in C++11, so you’ll need to enable that language set (or newer...
What Is a Range-Based For-Loop in C++? In programming, loops are used to repeat a block of code. When you know how many times you want to loop through a block of code, useforloop. The C++ range-based for-loop was introduced in C++11 as a concise notation for iteration over a con...
This post will discuss how to find the index of each value in a range-based for-loop in C++... The standard C++ range-based for-loops are not designed to get the index of each value.

With arrays taken care of by the first rule, the second rule makes sure that all the standard containers as well as all the user-defined ones that follow the standard sequence interface will work with range-basedforout of the box. For example, inODB(an ORM for C++), we have the contai...

However, because range-based for loops always iterate in a forwards direction and don’t skip elements, you can always declare (and increment) your own counter. However, if you’re going to do this, you should consider whether you’re better off using a normal for-loop instead of a range...
