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* FullAdderNew();

static void init(FacadeAdder *cthis) {
    cthis->fadder = (FullAdder*)FullAdderNew();

    cthis->carry_in = 0;
}
static int calculate(FacadeAdder *cthis, int a, int b) {
    int c2, sum, k;
    cthis->fadder->set_ab(cthis->fadder, a, b);

    k =c2 *10 + sum;
