1. Yes you can. In your particular case the replacement would look like

   ValeurColonne = new (char *)[10];

   The deletion is done with

   delete [] ValeurColonne;

   
   
2. The line is not entirely correct (except if one assumes there's additional code not showed here). ValeurColonne is an array, namely an array of char *. That is, each element of ValeurColonne is a pointer to char.Then your line is semantically equivalent to

   char * pChar=valuerColonne[i];
   strcpy(pChar,"Some text");

   The bug in the code is this: strcpy assumes that there's some allocated space pointed to by pChar where the string copying can be performed. As your code stands, pChar is null for all the positions of ValeurColonne, and a crash in your program is guaranteed.
