所以我很困惑如何重新洗牌。我编写了代码，并说card_t类型可以分配给int类型;我明白了，但我不知道还能做什么。
void reshuffle(shoe_t* shoe) {
int i, random_position = 0;
card_t arr[52* shoe->num_decks];
card_t temp;
printf("SHUFFLING!\n");
for(i=0; i< 52 * shoe->num_decks; i++) {
random_position = i + rand() % (52* shoe->num_decks - i);
temp = arr[random_position];
arr[random_position] = arr[i];
arr[i] = temp;
}
}
答案 0 :(得分：0)
arr被定义为int的数组。看起来你的意思是它是一个card_t的数组。您可能还希望在random_position中使用card_t temp = arr[random_position]之前初始化arr。
