Idiom #42 Continue outer loop
Print each item v of list a which in not contained in list b.
For this, write an outer loop to iterate on a and an inner loop to iterate on b.

Code
int *v = a; while (v < a+N) { int *w = b; while (w < b+M) { if (*v == *w) goto OUTER; ++w; } printf("%d\n", *v); OUTER: ++v; }
M is the length of b.
Using goto is usually considered bad practice in C.
