试图用另一个带有struct的函数调用一个函数

我有一个巨大的问题,我试图建立一些代码,我从另一个函数调用我的函数与结构在其中,但我不知道我是否已经混淆了自己,但我现在很丢失所以我会感谢som的帮助.基本上我试图做的是生成1到4之间的随机数,从那里我做了一些if语句,在if语句中我调用了我的函数.但是,它不能很好地工作. 它是最后一段错误的代码.功能"randomize()"

我得到的输出是心中的-939213(或所选颜色).我不知道如何解决这个问题,我根本没有解决方案.我会在这里得到一些帮助,并解决我的问题.而且仅供参考,我不想使用你可能看到的任何全局变量.

我看到的问题:

你是通过一个临时的地址Card的功能diamonds,spades等从randomize.

临时卡尚未初始化.

传递给其他函数的指针不是Cards 的套牌.它只是一个单一的Card.

建议解决问题.

传递变量deck从main到randomize.

将相同的变量传递给其他函数randomize.

首先更改函数原型:

void randomize(struct Card* deck);

更改来电main.

shuffleCards(deck);
randomize(deck);
printf("\n\n");

改变实施.

void randomize(struct Card* deck) {
   random_card = rand() % 4 + 1;

   if (random_card == 1) {
      hearts(deck);
   }
   if (random_card == 2) {
      diamonds(deck);
   }
   if (random_card == 3) {
      spades(deck);
   }
   if (random_card == 4) {
      clubs(deck);
   }
}
