A compiler is a special program that processes statements written in a particular programming language and turns them into a machine language that a computer processor can use.
A debugger is a special program that is used to find errors in other programs.It allows a programmer to stop a program at any point,examine and change the values of variables at any time.
An algorithm is a procedure for solving a problem in terms of the actions to be executed and the order in which the actions are to be executed

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.

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;
