我将对print_chars的调用替换为调试printf：

void draw_screen(){
 int y, x;
 for(y=0;y<=sizeY;y++){
  for(x=0;x<=sizeX;x++){
   if(grid[y][x] == 0){
    counter0++;
    if(grid[y][x+1] != 0 || x+1 >= sizeX){
     printf("grid[%d][%d] == 0; grid[%d][%d+1] != 0 || %d+1 >= %d; ", y, x, y, x, x, sizeX);
     printf("x=%d; y=%d; counter0=%d; counter1=%d\n", x, y, counter0, counter1);
     //print_chars(counter0, ' ', "BLACK");
     counter0 = 0;
    }
   }
   else{
    counter1++;
    if(grid[y][x+1] != 1 || x+1 >= sizeX){
     printf("!(grid[%d][%d] == 0); grid[%d][%d+1] != 1 || %d+1 >= %d; ", y, x, y, x, x, sizeX);
     printf("x=%d; y=%d; counter0=%d; counter1=%d\n", x, y, counter0, counter1);
     //print_chars(counter1, ' ', "WHITE");
     counter1 = 0;
    }
   }
  }
  //printf("\n");
 }
}

这将输出：

简而言之，if语句中的条件被满足了 * this * 多次，所以函数被调用了 * that * 多次，打印了 * that * 许多字符串。
我的建议是重新思考并简化你的逻辑。我真的不能给出任何额外的建议，因为我真的不明白你想要达到什么目的。我不知道你期望print_chars被调用多少次。如果你希望它只在grid[y][x] > 0时被调用，那么为什么不把它用作if条件呢？变量counter0，counter1和counter2对我来说真的很混乱。
补充意见：

• 如果您从未通过SetStdHandle()修改过标准输出句柄，那么您可以"缓存" GetStdHandle(STD_OUTPUT_HANDLE)的返回值，而不是反复调用. HANDLE stdout_handle = GetStdHandle(STD_OUTPUT_HANDLE);或类似函数。
• 你真的不应该像这样比较字符串。像"RED"这样的原始字符串在双等于比较中会"衰减"成一个指向该字符串的指针。正如**@Some Programmer Dude**所说，这个函数起作用的唯一原因是你调用这个函数时使用的字符串是byte-wise与要与之比较的字符串常量相同，并且编译器足够聪明，能够将两个示例解析为相同的（很可能是只读的）内存地址。在我看来，你要处理这个问题的方式，最好是使用enum color { GREEN, RED, BLUE, WHITE, BLACK, YELLOW };或类似的东西。
• 当你使用像if(color == "GREEN") { ... } else if(color == "RED") { ...这样的if-else-if链时，你可能会找到一种方法来使用一个开关大小写的结构来代替，但是不要感到有压力，这主要是为了风格。
• 当你malloc你的缓冲区，你应该做malloc(sizeof(char)*(size + 1))。这不是严格必要的，因为sizeof(char)将永远是1，除非在 * 非常奇怪 * 的情况下，但我提到它，因为你指定sizeof(char)。
• 如果不介意升级到C99，可以将声明int y, x;内联到for循环中，如for(int y=0; ...和for(int x=0; ...。
• 符号sizeX和sizeY是"宏"，在编译时被扩展。您应该考虑将grid声明为int grid[sizeX][sizeY];，以便更好地使用这些宏。还可以考虑将它们重命名为SIZE_X和SIZE_Y-似乎大多数C/C ++程序员都将宏设置为CAPSLOCKED_WITH_UNDERSCORES，以便更好地将它们与标识符区分开来。
• 如果在cmd下执行color /?，它会显示对应于cmd调色板中颜色的十六进制代码。您可以插入一个两位数的十六进制代码（就像color命令一样!）转换为SetConsoleTextAttribute，就像SetConsoleTextAttribute(conout_handle, 0xA0);一样，可以在黑色背景上获得明亮的绿色前景。还要注意的是，更现代的cmd版本并不 * 真的 * 受16-您也可以使用虚拟终端转义序列来指定颜色，并且\e[38;2;r;g;bm和\e[48;2;r;g;bm转义支持任意的r，g，b三元组。
• 提醒你一句：对输出格式化文本的问题越深入，混合C标准库函数和WinApi函数的问题就越大。特别是当Unicode支持进入画面时。我不希望你遇到任何可怕的问题，只是像这样弄乱颜色，但要注意如果你开始做 * 一堆 *非标准的东西，那么你的C标准库函数可能会不高兴。

我相信我已经解决了这个问题，你可以分层打印屏幕，而不是打印所有的东西，我们使用goTo()函数去任何需要打印值的地方，然后在那里运行算法，这样就避免了打印所有的0。

}

void print_chars(int size, char character, int r,int g, int b){ //Prints x number of spaces
  unsigned char* spaces = malloc(sizeof(char)*size + 1);
  memset (spaces,character,size);
  spaces[size] = '\0';
  //Colour options
  colorChar(r,g,b);
  fputs(spaces, stdout);
  free(spaces);
}

void draw_screen(int num, char character, int r, int g, int b){
 int y, x;
 for(y=0;y<sizeY;y++){
  for(x=0;x<sizeX;x++){

    }
    else{

     counter = 1; //There is a 1 instead of 0, this ensures that single characters are always printed
