Code demonstrating K&R's motivating example for `continue` doesn't need `continue`

continue.c

void process_nonnegative_elements(int a[], int n) {
    int i;
    for (i = 0; i < n; i++) {
        if (a[i] < 0) { /* skip negative elements */
            continue;
        }
        // ...  /* do positive elements */
    }
}

void process_nonnegative_elements_without_continue(int a[], int n) {
    int i;
    for (i = 0; i < n; i++) {
        if (a[i] >= 0) { /* skip negative elements */
            // ...  /* do positive elements */
        }
    }
}
