// Code-and-me class code, May 20th
// Goal: Create an image with evenly spaced horizontal lines

//  Step 3: Lets take advantage of the repetative nature of our code, and use a while{} statement for a loop

int h = 200;   // height
int w = 200;   // width
int yGap = 5; // the gap (on Y axis) to create between each line.
int yPos = 0;  // The variable that will define y position for each line.
int counter = 0;      // a counter variable for our loop  
int loopNum = h/yGap; // math for getting the number of lines to draw ..
                      // .. depending on the hight of our stage and the gap between each line

size(w,h);

while(counter < loopNum){
  //line(0,yPos, w,yPos);
  //line(200, 0, counter, yPos);
  line(0,0,200, yPos);
  yPos += yGap; // same as: ypos = ypos + yGap -->  set yPos to its own value plus yGap --> increase yPos by yGap 
  counter ++;
