我有一个代码,其中生成随机数的Colums = numCols和随机数的Rows = numRows。 nomRows和numCols的倍数= numCells。我想用一种不同的颜色给每个Cell着色,我知道我拥有的Cell总数,因为那是numCells。因此,我有一个数组“颜色”,具有6个值。该数组中的每个数字代表该数组中该颜色的显示次数和次数。我有一个循环,为每种颜色生成一个随机数,但始终确保数组中的总数不会比NumCells大。您不能总共有23个颜色值,并且只能容纳10个单元格。现在可以正常工作了,数组中的数字总数永远不会大于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 [],然后将其推入创建一个nother循环,该循环将向该数组中再添加2个数字,最后得到一个数组mysound2 []包含8个数字。
但是我无法正常工作,或者我得到一个错误:数组下标的无效类型'int [8] [int [6]]',我想arduino并不会插入到8的数组中,我只是试图添加6个数字。
或者,如果我尝试其他操作,代码将生成0,0,0。
请问如何将colors []放入mysoun2 []并添加2个随机数?

答案 0 :(得分:0)
我了解您想将一个阵列复制到另一个阵列中。您可以使用以下函数来做到这一点:
void copyArray(int* source, int* destination, int length) {
for (int i = 0; i < length; i++) {
*destination++ = *source++;
}
}
因此,如果要将colors
中的6个元素复制到mysound2
中,
copyArray(colors, mysound2, 6);
可以做到。
如果您想再添加2个元素,只需执行以下操作即可。
mysound2[6] = randNumber1;
mysound2[7] = randNumber2;
编辑::在注释部分中,您提到要将两个数组组合为一个。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++;
}
}
下面的代码会将colors
复制到mysound2
的前6个字节,并将thisPin
复制到mysound2
的后2个字节。
copyArray(colors, mysound2, 0, 6);
copyArray(thisPin, mysound2, 6, 2);
