I have a code in which I am generating random number of Colums = numCols and random number of Rows = numRows. The multiple of nomRows and numCols = numCells. I want to color each of the Cell by a different color, I know the total number of Cells I have, because that is numCells. Therefore I have an array "colors", which has 6 values. Every number in that array represents and how many times I have that color in that array. I have a loop which generates a randomm number for each color, but always making sure the total of the numbers in the array is never larger then NumCells. You cant have total 23 values for color and only 10 cells to fit it into. Now this works fine, the total amout of number in the array is never bigger than numCells.
So I have an array colors[] which contains 6 numbers, I want to push that array into mysound2[] and after I push it create a nother loop which will add 2 more numbers into that array to end up with an array mysound2[] which containts total number of 8 numbers.
But I can't get it working, either I get an error: invalid types 'int [8][int [6]]' for array subscript Which I guess arduino is not happt that into array of 8 I am only trying to add 6 numbers.
Or if I try something else the code generates 0,0,0.
Please how can I push colors[] into mysoun2[] and add 2 more random numbers?

I understand that you want to copy an array into another array. You can do that with a function like this:
void copyArray(int* source, int* destination, int length) {
for (int i = 0; i < length; i++) {
*destination++ = *source++;
}
}
So, if you want to copy 6 elements in colors into mysound2,
copyArray(colors, mysound2, 6); would do it.
If you want to add 2 more elements, just do something like this.
mysound2[6] = randNumber1;
mysound2[7] = randNumber2;
Edit: In the comment section, you mentioned that you want to combine two arrays into one. A function like this would do that.
void copyArray(int* source, int* destination, int destStartIndex, int len) {
for (int i = 0; i < len; i++) {
destination[destStartIndex + i] = *source++;
}
}
The code below will copy colors to the first 6 bytes of mysound2 and copy thisPin to the following 2 bytes of mysound2.
copyArray(colors, mysound2, 0, 6);
copyArray(thisPin, mysound2, 6, 2);
