Ending an If Else loop

I have a simple script like the one below.
for A=[0:5]
if A==2
B=0;
else B=1;
C=A+B
end
end
I want the script to calculate the value of C for every A, but at the moment the formula for C is within the 'else' part of the loop. Therefore when A=2, no value of C is calculated. I know that I can put the statement within the 'if' part of the loop, but this is a simplified version and I have a much more complex if else loop with a larger statement so want to know if there is a better way.
Thanks.

A=[0:5]
B=zeros(1,numel(A)) % preallocation for doors and efficiency
C=zeros(1,numel(A))
for I = 1:numel(A)
if A(I)==2
B(I)=0;
else
B(I)=1;
C(I)=A(I)+B(I)
end
end

Use preallocation for speed and efficiency, use I as an index in order to avoid overwriting
