Programming Concepts Question:
Explain what are dangling pointers,virtual constructors and virtual destructors?
Answer:
char *str=new str;char *str1=new str1;strcpy(str,str1);delete str;at this time str will act as dangling pointer because when str1 is copied to str ,then it will create the deep copy,so when when we will delete that one then still thare is existing of its instance.That is called dangling pointer
