This is the matrix:
1 1 1 1 1
0 1 0 0 0
0 0 1 0 0
0 0 0 1 0
0 0 0 0 1
so far I wrote B=ones(1,5); C=eye(4,5); A=[B;C]
But this command didn't come out right. Can someone please help me.

your command A = [B;C] concatenated them vertically.
Try:
C = eye(5)
C(1,:) = 1; % turns every element along the first row to 1.

I would like to clarify that I made the exact same changes right before I saw your comment!
Originally I had something like
C(1,:) = B;
