Answer with c++ linux coding please

Write a program named hw4pr2.cpp to draw a correct Texas flag using rectangles, lines, and/or polygons (not images). To draw a white 5-pointed star, first do a little trig to calculate the vertices and then map those points to window coordinates. Note: The official proportions of the Texas flag are as follows: each colored panel (red, white, and blue) has dimensions in the ratio 1 to 2, e.g., the blue panel is twice as tall as it is wide.
