C Program to Generate the graph sheet using the grphics.h library. To use graphics.h, we have to install the drivers in to the the system by using the initgraph() function. Here we derive the graph of input sizes verses time taken for input sizes. x axis represents inputs(0,10000,20000,—-), y axis rep time(0,0.05,0.1,0.15—). Read more about C Programming Language.

One comment on “C Program to generate Graph using grphics.h”
I’m impressed, I have to admit. Seldom do I come across a blog that’s both equally educative and engaging, and let me tell you, you’ve hit the nail on the head. The problem is something which too few folks are speaking intelligently about. Now i’m very happy I came across this during my hunt for something regarding this.
