Vertical graph In Lab 1 we plotted a histogram horizontally. In order to plot a histogram vertically, we need to have finished reading all the input before we start drawing the graph on the output. An array is suitable for this. A standard terminal window is 80 character-columns across. If we limit the number Of columns we can graph to a maximum Of 80, we know how large an array we need to allocate and this program is simple to write.
