c - printf C 错误

Question

所以我用 C 语言编写了这段代码，它应该打印如下所示的 map 。

printf ("(1)--------------------------------------------4T------5I        6P------7T-------------------------------------------(2)\n");
printf ("[%i]                                           [%i]     [%i]       [%i]     [%i]                                           [%i]\n", bs[1].leader, bs[4].leader, bs[5].leader, bs[6].leader, bs[7].leader, bs[2].leader);
printf (" \                                             |        \       /        |                                             / \n");
printf ("  \                                            |         \     /         |                                            /  \n");
printf ("   \                                           8T         \ 9T/         10T                                          /   \n");
printf ("    \                                         [ ]----------[ ]----------[ ]                                         /    \n");

问题是，它没有打印出来。它会跳过很多字符。有什么想法吗？

在 C 字符串中，需要将 \(即 "\\")加倍来表示一个 '\'。

所以你可以将代码编写为:

void pprint(){

    int bs[6];
    bs[0] = 7;
    bs[1] = 1;
    bs[2] = 2;
    bs[3] = 3;
    bs[4] = 4;
    bs[5] = 5;
    bs[6] = 6;

    printf ("(1)--------------------------------------------4T------5I        6P------7T-------------------------------------------(2)\n");
    printf ("[%i]                                           [%i]     [%i]       [%i]     [%i]                                           [%i]\n", bs[1], bs[4], bs[5], bs[6], bs[0], bs[2]);
    printf (" \\                                             |        \\       /        |                                             / \n");
    printf ("  \\                                            |         \\     /         |                                            /  \n");
    printf ("   \\                                           8T         \\ 9T/         10T                                          /   \n");
    printf ("    \\                                         [ ]----------[ ]----------[ ]                                         /    \n");
    printf ("     \\                                         |            |            |                                         /     \n");
    printf ("      \\                                        |            |            |                                        /      \n");

    printf ("                [ ]------------------------------------[ ]-[ ]-[ ]------------------------------------[ ]                \n");

}

请注意，如果没有替换(使用 %)，您可能应该更喜欢 puts() 而不是 printf() - 但请注意puts() 包含自己的最终换行符。
