我有一个代码,我在其中生成随机数列 = numCols 和随机数行数 = numRows。nomRows 和 numCols 的倍数 = numCells。我想用不同的颜色为每个单元格着色,我知道我拥有的单元格总数,因为那是 numCells。因此我有一个数组“颜色”,它有 6 个值。该数组中的每个数字代表我在该数组中有多少次该颜色。我有一个循环,它为每种颜色生成一个随机数,但始终确保数组中的数字总和永远不会大于 NumCells。您不能总共有 23 个颜色值,并且只有 10 个单元格适合它。现在这工作正常,数组中的总数永远不会大于 numCells。

所以我有一个包含 6 个数字的数组 colors[],我想将该数组推入 mysound2[] 并在我推入它之后创建一个另一个循环,该循环将在该数组中添加另外 2 个数字,最终得到一个数组 mysound2[]其中包含 8 个数字的总数。

但我无法让它工作,要么我得到一个错误:数组下标的无效类型'int [8] [int [6]]'我猜arduino不喜欢8的数组我只是想添加6个数字。

或者,如果我尝试其他方法,代码会生成 0,0,0。

请问如何将颜色[] 推入 mysoun2[] 并添加 2 个随机数?

我了解您想将一个数组复制到另一个数组中。你可以用这样的函数来做到这一点:

void copyArray(int* source, int* destination, int length) {
    for (int i = 0; i < length; i++) {
        *destination++ = *source++;
    }
}

因此,如果您想将 6 个元素复制colors到中mysound2copyArray(colors, mysound2, 6);请执行此操作。

如果您想再添加 2 个元素,只需执行以下操作。

mysound2[6] = randNumber1;
mysound2[7] = randNumber2;

编辑:在评论部分,您提到要将两个数组合并为一个。像这样的功能可以做到这一点。

void copyArray(int* source, int* destination, int destStartIndex, int len) {
  for (int i = 0; i < len; i++) {
        destination[destStartIndex + i] = *source++;
    }
}

下面的代码将复制colors到 的前 6 个字节mysound2并复制thisPinmysound2.

copyArray(colors, mysound2, 0, 6);
copyArray(thisPin, mysound2, 6, 2);
