Answer 1

In allocatematrix you allocate an array of length row of Arrays of length column (I suspect you forgot to translate the array Dimension ligne and colonne).
Later on you access as if it would be a continous memory Block you had allocated. This is Not the case!
Two solution ideas:
1. Really allocate one big chunck of raw memory and Do indexing for your own
Int* matrix=(*int) mallow(row*column*sizeof(int))
2. Access everywhere your Two Dimension separately, in reading, writing and free_memory. E. G. In allocatematrix
*((*(ptr+i)) +j) =val;
