C++ Range For Loop


title: Range For Loop

Range-based for loop

The ranged-based for loop allows easy looping over a range of elements (like elements in a container).

With traditional for loop:

std::vector<std::string> stringList {"one", "two", "three"}; for (size_t il; il < stringList.size(); il++ { std::cout << stringList.at(il) << std::endl; }

With range-based for loop:

std::vector<std::string> stringList {"one", "two", "three"}; for (auto& singleString : stringList) { std:cout << singleString << std::endl; }
