c - C语言中如何将两个数组字符串变成一个数组字符串

Question

如何将 2 个数组字符串变成 1 个数组字符串，这样我就可以打印出所有 52 张扑克牌？

我的代码:

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#include<string.h>


int main() {
    char deck[52];
    char suits[] = {"Hearts","Diamonds","Clubs","Spades"};
    char values[]= {"Ace","Two","Three","Four","Five","Six",\
                    "Seven","Eight","Nine","Ten","Jack",\
                    "Queen","King"};
    int V, S, d = 0;
    char string;
    for ( S= 0; S <4; S++) {
        for (V =0; V< 13; V++) {
            string = strcat( values[V], suits[S]);
            deck[d] = string;
            printf("%s\n", string);//prints out all the 52 playing cards
            d++;
        }
    }

    return 0;
}

当我执行程序时，出现问题，要求我调试程序或关闭程序，最终我关闭了程序，没有返回任何内容。您能给我有效的答案吗？

检查以下代码，该代码修复了代码中的问题:您的代码的问题是您尝试在打印之前修改实际的字符串，因此在下一次迭代中会有修改的字符串。因此，只需将值和花色复制到数组并打印出来，如下所示。

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#include<string.h>


int main()
{
  int i=0;
  char deck[30] = "";
  char suits[][30] = {"Hearts","Diamonds","Clubs","Spades"};
  char values[][30]= {"Ace","Two","Three","Four","Five","Six",
                    "Seven","Eight","Nine","Ten","Jack",
                    "Queen","King"};
  int V, S;
  for ( S= 0; S <13; S++)
  {
    for (V =0; V< 4; V++){
    memset(deck,0,sizeof(deck));/* Clear the buffer before writing new value*/
    strcpy( deck, values[S]);
    strcat(deck,suits[V]);
    printf("%s\n", deck);//prints out all the 52 playing cards
    i++;
   }
  }
    printf("Number of playing cards: %d\n",i);

    return 0;
  }
