从静态const结构返回const char **

static const struct A {
    int a1;
    const char ** a2;
} as[] = {
    {1,(const char *[]){\"LOL\",NULL}},
    {2,(const char *[]){\"LOL\",\"LOL2\",NULL}}
};

const char ** getA(int a) {
    int i = 0;
    for(;i< sizeof(as)/sizeof(struct A);i++){
       if (as[i].a1 == a)
           return as[i].a2;
    }
}
