Create x number of arrays

Question

Lets say I have this below.

int arrays = 0;

cin >> arrays ;

for(int i = 0; i < arrays ; i++)
{
        ????? Not sure what to do here.
}

And I want to create x number of arrays the user entered with 39 elements(40). How would I create this forloop to create 4 arrays? for example it would make array1 array2 array3 array4

Try creating vector of vectors instead: std::vector<std::vector<int> > vec; (also #include <vector>) check here for an example — nurettin

Vectors achieve a very similar thing. Must you use arrays? Have you been told to use arrays? — niemiro

int arrays = 0;

cin >> arrays ;

int *ptr = new int [arrays]; //Make sure to validate arrays against errors
                             //and don't forget to de-allocate using delete[] when done

for(int i = 0; i < arrays ; i++)
{
        ptr[i] = i;
}
