如何将2个不同数组中的数字组合成一个数组?

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?

// CODE FOR COLORS
``` int AnalogPin0 = A0; //Declare an integer variable, hooked up to analog pin 0
``` int AnalogPin1 = A1; //Declare an integer variable, hooked up to analog pin 1

void setup() {
  Serial.begin(9600); //Begin Serial Communication with a baud rate of 9600
  randomSeed(analogRead(0));

}

void loop() {
// 1)Gray, 2)White, 3)Yellow, 4)Blue, 5)Black, 6)Red

int numCols1  = random(1,4);
int numCols2  = random(2,5);
int numCols   = numCols1 + numCols2;

int numRows1  = random(2,5);
int numRows2  = random(2,6);
int numRows   = numRows1 + numRows2;

int numCells  = numCols * numRows;
int colors[]  = {5,3,2,1,0,0};
int numAlloc  = colors[0] + colors[1] + colors[2] + colors[3] + colors[4] + colors[5];


for (int i=0; i<numCells - numAlloc; i++)
{
  int color = random(0,7);
  color[colors]++;
}



  /*The Serial.print() function does not execute a "return" or a space
      Also, the "," character is essential for parsing the values,
      The comma is not necessary after the last variable.*/
Serial.print(colors [0]);     
Serial.print(",");
Serial.print(numCols);
Serial.print(",");
Serial.print(numRows);
Serial.print(",");
//Serial.print(numCells);
//Serial.print(",");
Serial.println();
delay(5000); // For illustration purposes only. This will slow down your program if not removed 
}

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);
