Please Help Me With Graph Task in C++

[zakaria2710]

Would u help me with this task, I am new in C++ programming, this codes have alot of errors, I have never work with graphs before, I am using Borlard C++ Ver 5.02. I was told u can not run a graph task using text editor. If that is the case how can I run this. I have only 7Days to handin this Task.

(a) Explain what process are being carried out by each method.
(b)Test this code on your system and report the outcome of your tests in a systematic manner. You need to provide a rationale for every test undertaken.
(c)Write a critical review of a given code and identify any strengths or weakness that may be present.
The Message Error I am getting when running this programme is : GRAPHICS.H(20.5 2); Error directive:BGI graphics not supported under windows.

Well, let's start with A. What do you think is being done by these functions?
