C:Loops - The Break And Continue Statement
(Page 4 of 4 )
Sometimes you may wish to break out of a loop even if the criteria has not been met to end the loop. Similarly you can force a program to reiterate a loop from the start, skipping over the elements of the loop following the Continue statement. Break also breaks out instantly from a loop, not bothering to carry out the rest of it. Here is an example with an infinite loop that counts to ten, then a continue forces it to count to 11, even though the break should (and eventually does) break out of the loop. Here it is:
#include <stdio.h>
int main()
{
int x=0;
for(;;)
{
x++;
if(x<=10)
{
printf("%d, ",x);
continue;
}
printf("%d is greater than 10 fool!n",x);
break;
}
return(0);
}
Here is the result of this program:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 is greater than 10 fool!
<Note: The for(;;) creates an infinite loop>
Conclusion
We didn't cover everything in this tutorial related to loops, such as nesting loops, but we did cover a lot of ground and will hopefully explain things in more detail further down the pipe. For now though you should have a good place to start on your programming. I'll be posting more articles in this series in the near future, so be sure to check back often. Thanks.
Till then...
