Write a script that will make x and y vectors. Then, it will ask the user for a color ('red', 'blue', or 'green') and for a plot style ('o', '*'). It will then make a string "pstr" that have the color and plot style, so that the call to the plot function would be: plot(x,y,pstr). For example, if the user enters 'blue' and '*', the variable "pstr" would have'b*'.
