if(i==3&&j==3&&k==3)
goto out;
else
printf("i=%d j=%d k=%d\n",i,j,k);

out:

Answer 1

You don't need the "if ... go out".
Three NESTED loops.
i = 1, j = 1, loop the k: 1, 2, 3
exits k, run loop j=2, start loop k, 1,2,3
exit k, run loop j=3, start loop k: 1, 2, 3
When loop j reaches 3, loop i does the next iteration: i = 2 and loop again.
When loop i reaches 3, all loops stop: exit.
