Social engineering; is the process of manipulating people to perform some action that will lead unauthorized users to break into a computer or network. This process is usually non-technical and relies heavily on human interaction and often involves tricking people to divulge confidential information e.g. passwords.

(Solved)
To illustrate exactly when an object is constructed and destructed when returned from a function, create a C++ class called who. Have who's constructor take one character argument that will be used to identify an object.Have the constructor display a message similar to this when constructing an object:
Constructing who #X
where x is the identifying character associated with each object when an object is destroyed, have a message similar to this displayed:
Destroying who #x
where, again, x is the identifying character. Finally, create a function called make_who() that returns a who object. Give each object a unique name.Note the output displayed by the program.

(Solved)
As you know, when an object is passed to a function, a copy of that object is made.Further, when that function returns, the copy's destructor function is called.Keeping this in mind, what is wrong with the following program?
// This program contains an error.
#include
#include
using namespace std;
class dyna {
int *p;
public:
dyna(int i);
~dyna() { free(p); cout << "freeing \n"; }
int get() { return *p; }
};
dyna::dy*) malloc(sizeof(int));
if(!p) {
cout << "Allocation failure\";
exit(1);
}
*p = i;
}
// Return negative value of *ob.p
int neg(dyna ob)
{
retur.get();
}
int main()
{
dyna 0(-10);
cout << o.get() << "\n";
cout << neg(o) << "\n";
dyna o2(20);
cout << o2.get () << "\n";
cout << neg (o2)\n";
cout << o.get () << "\n";
cout << neg (o) << "\n";
return 0;
}

(Solved)
Given the following base C++ class,
class area_cl {
public:
double height;
double width;
};
Create two derived classes called rectangle and isosceles that inherit area_cl. Have each class include a function called area()
that returns the area of a rectangle or isosceles triangle, as appropriate. Use parameterized constructors to initialize height and width.
