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;
}
