3.2    Control Flow

Control flow (or the flow of control) refers to the order in which individual statements, instructions are executed or evaluated in a program. In this section, we’ll go over the fundamental control flow construct called a loop and its different types. You’ll use loops to handle repetitive tasks efficiently.

3.2.1    Simple Loops

The first type of loop is simply a loop. The code after this loop construct executes forever. For instance, the following code will execute infinitely:

loop {        println!("Simple loop");}  

This code will print Simple loop forever. To exit out of a loop, you can use a break statement, as in the following example:

loop {        println!("Simple loop");        break;}  

If you have nested loops (i.e., a loop containing ...
