clc;
I=imread('b2.bmp');
figure(1),imshow(I);
I=double(I);
[M,N] = size(I);
% blue_mask = repmat([1 0; 0 0], M/2, N/2);
% green_mask = repmat([0 1; 1 0], M/2, N/2);
% red_mask = repmat([0 0; 0 1], M/2, N/2);
%
% R=I.*red_mask;
% G=I.*green_mask;
% B=I.*blue_mask;
B = I(1:2:end,1:2:end);
G1 = I(1:2:end,2:2:end);
G2 = I(2:2:end,1:2:end);
R = I(2:2:end,2:2:end);
G = (G1+G2)/2;
figure(2), imagesc(R);
figure(3), imagesc(G);
figure(4), imagesc(B);
final(:,:,1)=R;
final(: ,:,2)=G;
final(: ,:,3)=B;
final=double(final);
final=final*125/15;
final=uint8(final);
% imshow(final)
% I = imread('b2.bmp');
% J = demosaic(I,'bggr');
% imshow(I);
% figure, imshow(J);

The computations should be fairly easy.
You will have to find some kind of graphics library to do the figure() and imagesc() parts, as graphics is not part of C and cannot be implemented in standard C.
Reading BMP images is not part of the C language, but you should be able to find a third party library to do the reading for you, as that part can be implemented in standard C
