Iterative statements

During software development, you might need to process or handle each element of the collection such as an array or a map. Sometimes, you will want to access each element of the collection and change its value or just read it for further processing. In V, you can achieve this by writing iterative statements using for loops.

The for loop, which is used as an iterative statement in V, is used to iterate over the elements of a collection. The collection is generally an array that has elements of a certain data type, or it could be a map that holds data in the form of key-value pairs.

In this section, we will examine the very basic syntax of how to write a for loop in V. Then, we will explore various ways in which to work with for loops, including how to write the following:

• A for loop on maps
• A for loop on arrays
• A for loop without an index on the array
• A traditional C-style for loop
• A reverse for loop
• A for loop on a range
• A...
