Laboratory on C++

You need to do the lab work on C++. In laboratory work, it will be necessary to operate arrays. I'm not going to bother you, the assignments are as follows:
1. Create a 5x5 dimanic array;
2. Fill the array with different numbers;
3. Sort the array with a snake from top to bottom;
4. Expand the array to 5x5x5;
5. Fill it again with different numbers;
6. Sort the 3-dimensional array by main and side diagonal.
