Feb 02, 2016 If you are using Microsoft windows 7 operating system,Then Dev C is good for beginner, It fallow the same command as it is in Turbo C, First Download the Dev C and install it. After installation download WinBGIm. And Install it. Now open Dev C. FileNewProject.WinBGIm WinBGImWrite Project Name; When you clicked on OK, there will open a file containing some pre. How to visualize/plot a graph in C? Ask Question Asked 6 years, 1. I would like it to be in C. Also, plotting a graph is something I want to do just for fun and has no further use. Boost is considered the bleeding edge of c development. If you want to look at what a simple-yet-powerful interface might look like, dot might inspire.

Hi.
I have to make a program in c++ for plotting a sine curve.using arrays .in horizontal direction not vertical .
can I have an alogarithm or just a hint how to go on making ..thanks :)

How To Draw Graph In Dev C++
It depends how sophisticated you want to get. If it is a simple text based console program, you can make an array of strings. Each string contains let's say eighty characters, all spaces but for one asterisk. It will be your genius to place the lonely asterisk at the right position according to y = sin(x). Centrify for mac sierra. Print out about 50 strings with a new line each, and you have the rudimentary look of a sine function. Dbz xenoverse 2 download mac.
