facadeadder.c

基于ANdroid平台的高欢堂书籍的对应源代码 非常有用

/*    FacadeAdder.c    */
#include "FacadeAdder.h"
extern void* HalfAdderNew();

static void init(FacadeAdder *cthis) {
    cthis->hadder = (HalfAdder*)HalfAdderNew();
}
static int calculate(FacadeAdder *cthis, int a, int b) {
    int c, s, k;
    cthis->hadder->set_digits(cthis->hadder, a, b);
    cthis->hadder->run(cthis->hadder);
    c = cthis->hadder->get_carry(cthis->hadder);
    s = cthis->hadder->get_sum( cthis->hadder);
    k =c *10 + s;
    return k;
}
