Question

I am trying to declare an array of pointers each of which points to int arrays of different sizes. Any ideas?

Answer 1

From your description it sounds like you are looking for a pointer to a pointer.

int **aofa;
aofa = malloc(sizeof(int*) * NUM_ARRAYS);
for (int i = 0 ; i != NUM_ARRAYS ; i++) {
    aofa[i] = malloc(sizeof(int) * getNumItemsInArray(i));
}
for (int i = 0 ; i != NUM_ARRAYS ; i++) {
    for (int j = 0 ; j != getNumItemsInArray(i) ; j++) {
        aofa[i][j] = i + j;
    }
}

NUM_ARRAYS arrays may have different number of elements, as determined by the value returned by the getNumItemsInArray(i) function.
