C++ (Cpp) rb_update Examples

Example #1

File: main.c Project: pronan/c_data_structures

static void
test_rb(void) {
    //rbtree *tr = rb_cnew( 0, 0, 0, 0, 0, 0);
    rbtree *tr = rb_new();
    char keybuf[100];
    size_t valuebuf[] = { 1 };
    size_t *vp;
//    while (fscanf(stdin, "%s", keybuf) == 1) {
//        vp = rb_get(tr, keybuf);
//        if (vp)
//            *vp += 1;
//        else
//            rb_add(tr, keybuf, valuebuf);
//    }
//    this is another faster version
    while (fscanf(stdin, "%s", keybuf) == 1) {
        vp = rb_fget(tr, keybuf);
        *vp += 1;
    }
    rb_set(tr, "a", valuebuf);
    *valuebuf = 123456789;
    rb_add(tr, "b", valuebuf);
    *valuebuf = 2;
    rb_set(tr, "c", valuebuf);
    rb_set(tr, "d", valuebuf);
    *valuebuf = 987654321;
    rb_update(tr,"a",valuebuf);
    rb_set(tr, "e", valuebuf);

    rb_print(tr);
    rb_clear(tr);
    rb_clear(tr); //just for test
    rb_free(tr);
}
