continue statement, like
break, is used only inside
while loops. It skips over the rest of the loop
body, causing the next cycle around the loop to begin immediately.
Contrast this with
break, which jumps out of the loop altogether.
Here is an example:
# print elements of a vector of random # integers that are even. # first, create a row vector of 10 random # integers with values between 0 and 100: vec = round (rand (1, 10) * 100); # print what we're interested in: for x = vec if (rem (x, 2) != 0) continue; endif printf ("%d\n", x); endfor
If one of the elements of vec is an odd number, this example skips the print statement for that element, and continues back to the first statement in the loop.
This is not a practical example of the
continue statement, but it
should give you a clear understanding of how it works. Normally, one
would probably write the loop like this:
for x = vec if (rem (x, 2) == 0) printf ("%d\n", x); endif endfor
