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);
}
