Preface

Iteration statements


Iteration statements repeat a block either while a condition is true or for each item in a group. The choice of which statement to use is based on a combination of ease of understanding to solve the logic problem and personal preference.

Use either Visual Studio 2017 or Visual Studio Code to add a new console application project named Ch03_IterationStatements.

In Visual Studio 2017, you can set the solution's start up project to be the current selection so that the current project runs when you press Ctrl + F5.

The while statement

The while statement evaluates a Boolean expression and continues to loop while it is true.

Type the following code inside the Main method:

    int x = 0; 
    while (x < 10) 
    { 
      WriteLine(x);

    } 

Run the console application and view the output:
