Graphics Editor code Using C++ Language
Write a Graphics Editor program to develop a graphics editor which includes features like line draw, rectangle draw,circle draw, pie chart draw,ellipse draw,polygon draw,bard raw, pixel draw,text draw etc.
Graphics Editor have a menu for user interaction from which user can provide input to program.By selecting appropriate option user will get output.
