// For Loop Example

  // The Same while loop from the previous example
  int x = 0;  // Step 1
  while (x < width)  // Step 2
  {
    line(x,0,x,height);  // Draw a line the entire height of the window and at the x point    
    x = x + 10; // Step 3
  }
  */
  
  // Do all steps at once in a "for" loop
  // Read this as:  for x equals 0, while x is less than width, increase x by 10
  for (int x = 0; x <  width; x = x + 10)
  {
    // Does the exact same thing as the while loop above but more commonly used this way
    line(x,0,x,height);
