The program should allocate memory for a square matrix

# include & lt; stdlib.h & gt;
bool WidPam (int ** X, int str, int sto)
{
  if (! (X = (int **) calloc (str, sizeof (int *))))
  {
    printf ("Not enough memory \ n");
    return false;
  }
  for (int i = 0; i & lt; str; i ++)
  {
    if (! (/ * The cursor is here * / (X + i) = (int *) calloc (sto, sizeof (int))))
    {
      printf ("Not enough memory \ n");
      return false;
    }
  }
  return true;
}

The error means that the X + i on the left side of the assignment is nonsense. What were you trying to achieve by your trying to assign something in X + i ?

The result of the expression X + i is not an lvalue. You cannot assign anything to it.
