我创建了一个数组和一些函数，每个函数均打印不同的模式。我的问题是它们以怪异的方式打印在阵列内部。下面是代码的主要部分，仅是示例的一个函数。
int castle(int patternWidth, int doorStart, int doorEnd, int N, int i, int j, int row, int col, char** array)
{
if (N >= 3 && N <= 20)
{
for (i = 1; i <= (N + 1); i++)
{
array[row][col] = '*'; col++;
array[row][col] = ' '; col++;
}
row++;
patternWidth = (((N + 1) * 2) - 1);
doorStart = (patternWidth - 3) / 2;
doorEnd = doorStart + 3;
for (i = 0; i < N; i++)
{
for (j = 1; j <= patternWidth; j++)
{
if(N - i <= 2 && j > doorStart && j <= doorEnd)
{
array[row][col] = ' '; col++;
}
else
{
array[row][col] = '*'; col++;
}
}
row++;
}
}
return 0;
}
int main()
{
int N = 0, M = 0, i = 0, j = 0, a = 0, b = 0, s = 0, width = 0, height = 0, patternWidth = 0, doorStart = 0, doorEnd = 0, option = 0, num = 3, col = 0, row = 0;
char** array;
printf("Give height board size:");
scanf("%d", &height);
printf("Give width board size:");
scanf("%d", &width);
array = (char**)malloc(height * sizeof(char*));
for (i = 0; i < width; i++)
{
array[i] = (char*)malloc(height * sizeof(char));
}
for (i = 0; i < height; i++)
{
for (j = 0; j < width; j++)
{
array[i][j] = ' ';
}
}
while (option != 6)
{
printf("\nOption: 1-5, 6 to exit\n"
"1) Stairs and flag\n"
"2) Castle\n"
"3) Trap door\n"
"4) Platform\n"
"5) Obstacles\n"
"Option:");
scanf("%d", &option);
if (option == 1)
{
printf("Valid values 6 - 20\n");
printf("Size:");
scanf("%d", &N);
printf("Height Position:");
scanf("%d", &row);
printf("Width Position:");
scanf("%d", &col);
stairs_flag(N, i, j, b, a, num, col, row, array);
}
else if (option == 2)
{
printf("Valid values 3 - 15\n");
printf("Size:");
scanf("%d", &N);
printf("Height Position:");
scanf("%d", &row);
printf("Width Position:");
scanf("%d", &col);
castle(patternWidth, doorStart, doorEnd, N, i, j, row, col, array);
}
else if (option == 3)
{
printf("Valid values 3 - 18\n");
printf("Size of N:");
scanf("%d", &N);
printf("Height Position:");
scanf("%d", &row);
printf("Width Position:");
scanf("%d", &col);
trap_door(N, patternWidth, i, j, col, row, array);
}
else if (option == 4)
{
printf("Valid values of N 3 - 20\n");
printf("Size of N:");
scanf("%d", &N);
printf("Valid values of M 6, 8, 10, 12, 14, 16, 18, 20\n");
printf("Size of M");
scanf("%d", &M);
printf("Height Position:");
scanf("%d", &row);
printf("Width Position:");
scanf("%d", &col);
platform(N, M, i, j, col, row, array);
}
else if (option == 5)
{
printf("Valid values 2 - 10\n");
printf("Size of N:");
scanf("%d", &N);
printf("Height Position:");
scanf("%d", &row);
printf("Width Position:");
scanf("%d", &col);
obstacles(N, i, s, j, patternWidth, row, col, array);
}
print_array(array, height, width);
}
free(array);
return 0;
}

例如，在上面的两个阵列中，木板的宽度为60，高度为20，对于图案，我将高度和宽度的位置都设置为10。模式的每一行都应该在前一行之下，并打印一个模式，但实际上，它在前一行之下打印每一行，但比前一行更多。我该如何纠正？功能代码是否有任何错误。对于每个功能，我都做相同的事情。我将array[row][col] = '*'; col++;标记为星号，将array[row][col] = ' '; col++;标记为空格，并将row++;标记为新行。
谢谢您的时间

问题似乎是您的列索引col在整个castle()函数中一直在增加。如果希望星号彼此对齐，则需要在for循环开始时将列索引设置回其原始值。
例如，您可以做到
int castle(int patternWidth, int doorStart, int doorEnd, int N, int i, int j, int row, int col, char** array)
{
int column_index = col;
if (N >= 3 && N <= 20)
{
for (i = 1; i <= (N + 1); i++)
{
array[row][col] = '*'; col++;
array[row][col] = ' '; col++;
}
row++;
patternWidth = (((N + 1) * 2) - 1);
doorStart = (patternWidth - 3) / 2;
doorEnd = doorStart + 3;
for (i = 0; i < N; i++)
{
for (j = 1; j <= patternWidth; j++)
{
col = column_index;
if(N - i <= 2 && j > doorStart && j <= doorEnd)
{
array[row][col] = ' '; col++;
}
else
{
array[row][col] = '*'; col++;
}
}
row++;
}
}
return 0;
}
我在其中添加了一个命令int column_index = col;，该命令将原始值存储在函数的开头，在行col = column_index;的内部for循环的开头，将存储的值放回变量。
