Use Arrows to Draw Vectors
Problem Statement:
Use the arrow tools to add a vector W = <2,8> on the grid. Then add another vector represents the sum of U and 2*W

#include <chplot.h>
CPlot plot;

plot.arrow(0, 0, 9, 4);
plot.text("U", PLOT_TEXT_LEFT, 4, 0);
plot.strokeColor("green");
plot.arrow(9, 4, 11, 12);
plot.text("W", PLOT_TEXT_LEFT, 10.5, 7);
plot.line(9, 4, 13, 20);
plot.strokeColor("blue");
plot.arrow(0, 0, 13, 20);
plot.text("U+W", PLOT_TEXT_LEFT, 1, 9);

plot.axisRange(PLOT_AXIS_XY, -12, 24);
plot.ticsRange(PLOT_AXIS_XY, 6);
plot.sizeRatio(1);
plot.plotting();```
