A statement under "for" gets skipped during the last loop

function coded = caesar (v,s)
    coded=v;
    count=0;
    for ii = v+s
        count=count+1;
        if (ii>126)
            ii=32+(ii-126-1);
        else if (ii<32)
            ii = 126-(32-ii-1);
        end
        coded(count)=ii;
        end
end 

The above given code is made for a decoder and an encoder so when i execute it, the code works fine until it reaches the end of the string (v+s) , at the end it seems the variable ii is assigned a value "the right one" but the statement " coded(count)=ii " does not run (the loop skips it the last iteration) , is there something i am missing here.

the input i gave is mentioned below

caesar('~',1)

and coded returns the value '~' instead of ' '

YOu are changing the loop index ii inside the if...else statements.......that is now allowed...

function coded = caesar (v,s)
    coded=v;
    count=0;
    for ii = v+s
        count=count+1;
        jj = ii ; 
        if (ii>126)
            jj = 32+(ii-126-1);
        else if (ii<32)
            jj = 126-(32-ii-1);
        end
        coded(count)=jj;
        end
end
