How do I display only the last iteration

I need to find the sum and average of values in a vector without using the mean or sum function, using a FOR loop statement. Let's say my vector is x =[1:1:20]. So far, I have

theSum = 0;
for k =1:length(x);
      theSum = theSum + x(k);
    fprintf('The total value of x is %.1f, and the average value of x is %.3f\n\n',...,
theSum, theSum/k);
end

I only want to display the final iteration. I'm guessing I need to use the break command, but I don't know how to or where in my statement.

Move the fprintf to after the loop:

theSum = 0;
for k = 1:numel(x);
    theSum = theSum + x(k);
end
fprintf('The total value of x is %.1f, and the average value of x is %.3f\n\n',...,
theSum, theSum/k);

x='8453365';

theSum = 0;

for k =1:length(x)

theSum = theSum + x(k);

end

disp([theSum, theSum/length(x)])
