In the first year of engineering, we were taught C by Madam Humera Noor. She was a nice teacher and introduced us about every element of C, from basics to advanced, from Text mode to Graphics, from structures to unions, from File IO to port addressing, from Pointers to variables to pointers to functions, and many more. I was able to make some logic games in C. As the final project of C, I made a Graph Plotter which was very appreciated by teachers and class fellows. The program inputs an expression from user and plots its graph in rectangular as well as polar mode. I further transformed the same program in VB also.
