Draw Static Colorful Twinkle Stars
Problem Statement:
The pre-placed block will draw one star of any random color and length 2.5 in given x- and y-coordinate. Use set variable and random integer blocks to plot 50 stars at random x- and y-coordinates between 1 and 35. Also, change the length of the star block in order to draw the stars of different lengths.
```/* Code generated by RoboBlockly v2.0 */
#include <chplot.h>
double x;
double y;
double length;
CPlot plot;
int count;

//plot.backgroundImage("stars.png");
count = 0;
while(count < 50) {
plot.noStrokeColor();
plot.fillColor(randcolor());
x = randint(1, 35);
y = randint(1, 35);
length = randint(1, 2.5);
plot.star(x, y, length, 0);
count = count + 1;
}
plot.grid(PLOT_OFF);

plot.axisRange(PLOT_AXIS_XY, 0, 36);
plot.ticsRange(PLOT_AXIS_XY, 6);
plot.sizeRatio(1);
plot.plotting();
