function coded=caesar(str,shift) a=double(str); counter=1; coded=zeros(1,length(str)); for i=[1:length(str)] if a(1,couner)+shift>126||a(1,counter)+shift<32%j while a(1,couner)+shift>126 coded(1,counter)=a(1,counter)+shift-95; counter=counter+1; end while a(1,counter)+shift<32 coded(1,counter)=a(1,counter)+shift+95; counter=counter+1; end else coded(1,counter)=a(1,counter)+shift; counter=counter+1; end end coded=char(coded) end

I tried it now but it seems like it's not working yet,I got this message...Index in position 2 exceeds array bounds (must not exceed 4).

Error in caesar (line 7) while a(1,counter)+shift>126 Please help!!

solution:

save it :

function coded=caesar(str,shift) 
a=double(str);
counter=1; coded=zeros(1,length(str)); 
for i=[1:length(str)] 
    if a(1,counter)+shift>126||a(1,counter)+shift<32%j 
        while a(1,couner)+shift>126 
            coded(1,counter)=a(1,counter)+shift-95; 
            counter=counter+1; 
        end
         while a(1,counter)+shift<32 
             coded(1,counter)=a(1,counter)+shift+95; 
             counter=counter+1;
         end
    else
        coded(1,counter)=a(1,counter)+shift; 
        counter=counter+1; 
    end
end
coded=char(coded);
end
