c - 如何打印 2D 战舰游戏

Question

我正在尝试为玩家一制作一张打印的战舰 map 。这是我编写的代码。

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#define W  '~'
#define H  '*'
#define M  'm'

#define C     'c'
#define B     'b'
#define R     'r'
#define S     's'
#define D     'd'

void printBoard() {
 for (int x = 0; x < 10; x++) {
    printf("         | ");
    for (int y = 0; y < 10; y++) {

        if (player1Side[x][y].aim != 0) {
            printf("%c", player1Side[x][y].visuals);
        }
        else {
            switch (player1Side[x][y].visuals)
            {
            case H: printf("%c", H);
                break;

        }
        scanf("%d %d", &x, &y);
        if (a - 1 >= 10 || b - 1 >= 10 || (a + s.size >= 10 && isVert!=true) || (a + s.size >= 10 && isVert == true)){
            printf("That is out of bounds. please try again\n");
            placeShips();
            break;

  }

return true;


}

main() {

    for (int x = 0; x < 10;x++) {
      for (int y = 0; y < 10;y++) {
        player1Side[x][y].aim = 0;
        player2Side[x][y].aim = 0;
        player1Side[x][y].visuals = '~';
        player2Side[x][y].visuals = '~';
    }
   }
  printBoard();
  placeShips();
  printBoard();
  system("pause");


  }

当我运行它时，我希望在输入的坐标中获得船舶的符号。但相反，我明白了。

这真的很烦人，已经连续困扰我几个小时了。谁能帮帮我吗？我真的很感激。

查看代码，您似乎应该将结构中的 type 视为 char 而不是 int

typedef struct{
    int size;
    char type;   // <== not int
} Ship;

然后还有一些指针混淆。 placeShips

while(c < 1) {
    isVert = false;
    scanf("%c %c", i, &nS->type); // <== not &i 

以及切换之后

    scanf("%d %d", x, y); // <== not &x &y

稍后为

    player1Side[a + i - 1][b].visuals = nS->type; // <== not &
}
else {
    player1Side[a][b + i - 1].visuals = nS->type; // <== not &

仅供引用，正在做

int z;
int *p = &z;

使p指向z地址，因此在scanf中直接使用p而不是&p .

修复这些后，电路板应该看起来更好。
