"the input character is not valid"

I started writing this program, but the #include at the top of the screen didn't light up. See my program below: http://s716.photobucket.com/user/Pitoraq/media/include_zps5796d485.png.html Im beginner in Matlab so i dont know how to fix it :(

Your code is in C. Try writing it in MATLAB language.

PS: You can insert images on this forum too, although the best idea is to paste your code as text, and use the text formatting. Have a look at the formatting tools above the text field.

I tried it on Eclipse in c project and it didnt work either.

Your code is a very simple C program which compiles fine for me (Visual studio with a very small modification to account for a fact that VS doesn't define M_PI).

Find an eclipse support forum if you need help getting it to compile.

matlab and C are two completely different language. Your program is in the C language. What made you think it would work in matlab?

Also, please don't post images of your code. Just copy-paste in the question (and use the code formatting button).
