I have created a graph(map) using graphics.h in C. Just to mentioned I have coordinate location of each and every point on the map.
How can I zoom in to the particular area selected by the user ?
Secondly, how can I zoom in around a particular point(selected by the user) on the graph(map) ?
most people around here haven't used <graphics.h> for about 15 years. it's way obsolete now.
so, sorry, you probably won't get much help.
you should ask your instructor why he doesnt teach you how to use a modern graphics libraray, like GTK or OpenGL.
That depends a lot on how you have the data designed and a host of other stuff. Details are necessary.
