我有一个生成随机列数= numCols和随机行数= numRows的代码。nomRows和numCols = numCells的倍数。我想用不同的颜色给每个单元格着色,我知道我有多少个单元格,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都表示该颜色在该数组中出现的次数。我有一个循环,它为每种颜色生成一个随机数,但始终确保数组中数字的总和永远不会大于NumCells。你不能总共有23个颜色值,而只有10个单元格可以容纳它。现在这样做很好,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[],并在推入后创建另一个循环,该循环将向该数组中再添加2个数字,最终得到一个包含8个数字的数组mysound2[]。
但是我不能让它工作,或者我得到一个错误:数组下标的类型'int 8int 6]‘无效,我猜arduino不会很高兴,因为我只想添加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colors[]推送到mysoun2[]中,并再添加2个随机数?
