To implement the Digital Differential Analyzer (DDA) Line Generation algorithm in C/C++ using OpenGL, we need to set up a basic OpenGL environment and then apply the DDA algorithm to generate lines. Here's a step-by-step guide on how to do it:

1. Setting up the OpenGL Environment:
   - Include necessary OpenGL headers.
   - Initialize OpenGL window and set up the viewport.

2. Implementing DDA Line Generation Algorithm:
   - Define a function to draw a line using DDA algorithm.
   - Calculate the slope of the line `(m)`.
   - Determine whether the line is steep (`|m| ___ _______ ________ _______ _______ _________ _____ __________ ________.
