Foreach Loops

Runs a block of code for each item of an array or list.

A variable is created after the type of loop to store the current item in an array.

Found in languages like C# and Python .

Use this kind when you want the same exact action to occur for each item.

Foreach loop examples

C# and Unity:

string[] names = { "Fluffy", "Nugget", "Pumpkin" };

foreach (int item in names) {
    println(item);
} 

Python:

names = [ "Fluffy", "Nugget", "Pumpkin" ]

for item in names:
    print(item \n)

Both will print:

Fluffy Nugget Pumpkin

Here:

  1. Type: foreach or for (line 3)

  2. Initialization: int item and item (line 3)

  3. Conditions: (int item in names) or item in names (line 3) (only runs the loop code when there is an item to run the code with)

  4. Update: in names (line 3) (moves to the next item)

  5. Action: println(item); or print(item \n) (line 4) (prints the current item based)

Note: \n is another way to do a carriage return (end the line in the printed message)
