To understand the significance of virtualdestructor, consider the following example in C++: #include<iostream>usingnamespacestd;classBase{public:Base(){cout<<"Base Constructor \n";}~Base(){cout<<"Base Destructor \n";}};classDerived:publicBase{public:int*n;Derived(){cout<<"Derived Constructor...
printf ("offsetof(S1, employee) is %d/n", offsetof(S1, employee));printf ("offsetof(S1, title) is %d/n", offsetof(S1, title));printf("s1.title's address is %x ==> s1's address is %x/n", td, k);return 0;}/* Example 1 Output */offsetof(S2, singlechar) is 0offsetof(S2,...

Linear in size of the container, i.e. O(N) Example The following example shows the usage of std::set::~set() destructor. Open Compiler #include <iostream> #include <set> #include <string> using namespace std; int main(void) { //Default constructor std::set<string> t_set; t_set...
Notice that the following example code prints two destructor messages, one of which is triggered by the explicit user call, and the other is automatically called on program exit. Although, if theMyClassdata member was allocated with thenewoperator in the constructor, this example would have led...
