The following macros will facilitate this task and have been very useful:
#define SAFEDELETE(p) if(p) { delete p; p =NULL;}
#define SAFEDELETE_ARRAY if(p) { delete [] p; p = NULL;}
How to use-
int main()
{
int *i = new int;
char *ptr = new char[100];
// do something with ptr
SAFEDELETE_ARRAY(ptr);
SAFEDELETE(i);
}
