printf C出错

Question

所以我在C中有这个代码，应该打印下面显示的地图。

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");

问题是，它不打印。它会跳过很多字符。有任何想法吗？

在C字符串中，你需要加倍\（即"\\"）来代表一个'\'。

所以你可以编写你的代码：

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");

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