如何打印2d战舰游戏

Question

我试图为玩家一制作打印的战舰地图。这是我制作的代码。

#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'

}Ship;
Space player1Side[10][10];
Space player2Side[10][10];
Ship s, *nS;
int a, b;

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;

            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;
        }
        else {

  }
  boolean checkWinner() {

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得到一个船的符号。但相反，我明白了。

它真的很烦人，一直困扰着我好几个小时。谁能帮帮我吗？我真的很感激。

Answer 1

查看代码时，您似乎应该在结构中将type视为char而不是int

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

然后有几个指针混淆。在 placeShips

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

并在开关

之后

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

后面的

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

仅供参考，

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。

通过这些固定，电路板应该看起来更好。
