Understanding iteration statements

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

Looping with the while statement

The while statement evaluates a Boolean expression and continues to loop while it is true. Let’s explore iteration statements:

  1. Use your preferred code editor to add a new Console App / console project named IterationStatements to the Chapter03 solution.
  2. In Program.cs, delete the existing statements, and then add statements to define a while statement that loops while an integer variable has a value less than 10, as shown in the following code: 
    int x = 0;
while (x < 10)
{
  WriteLine(x);
  x++;
}
  3. Run the code and view the results, which should be the numbers 0...
