Foreach Loops

Foreach loops can be used to iterate over containers, that offer iterator implementations like Vector, ArrayList, etc. as well as arrays of arbitrary elements and number ranges.

Usage¶

You can write foreach loops in two different ways:

Ordinary¶

If you only need the item to work with, the recommended way is to use the ordinary foreach loop:

int[7] myIntArray = { 1, 5, 4, 0, 12, 12345, 9 };
foreach (const int item : myIntArray) {
    printf("Item: %d", item);
}

Indexed¶

As soon as you need to access the index of the current item as well, you can use the indexed foreach loop:

dyn welcomeMessage = Vector<string>();
welcomeMessage.pushBack("Hello");
welcomeMessage.pushBack("fellow");
welcomeMessage.pushBack("Spice");
welcomeMessage.pushBack("programmers!");
foreach long idx, string word : welcomeMessage {
    printf("Word no. %d: %s\n", idx, word);
}
