Editing Conditional loop (section)

===For-Each loop===
A for-each loop is essentially equivalent to an [[iterator]]. It allows a program to iterate through a data structure without having to keep track of an index. It is especially useful in Sets which do not have indices. An example is as follows:

<syntaxhighlight lang="c++">
std::vector<std::string> range = { "apple", "banana", "orange" };

for (auto item: range) {
    // code
}
</syntaxhighlight>
