Using a Friend
Using a friend function is quite easy. The following example explains a friend function to access members of two classes.
class Bclass; // Forward Declaration
class Aclass
{
public :
Aclass(int v)
Avar = v;
}
friend int addup(Aclass &ac, Bclass &bc);
private :
int Avar;
};
class Bclass
Bclass(int v)
Bvar = v;
int Bvar;
int addup(Aclass &ac, Bclass &bc)
return( ac.Avar + bc.Bvar);
void main()
Aclass aobj;
Bclass bobj;
int total;
total = addup(aobj,bobj);
for object, malloc allocates memory in heap however doesn't invoke object's constructor to initialize the object. new allocates memory & also invokes constructor to initialize the
// Basic pointer code #include "stdafx.h" #include iostream using namespace std; int _tmain(int argc, _TCHAR* argv[]) { int FirstNumber, SecondNumber;
Can a copy constructor admit an object of the similar class as parameter, rather than reference of the object?
what is programming?
polishing the jewel game with c coding
check this link: http://cactus.eas.asu.edu/partha/Teaching/430.2013/Project/proj-2.2013.htm
Program is to read the contents of a file: void main() { ifstream fin("ascii.txt"); char ch; while(! fin.eof()) { fin>>ch; cout }
#include "stdafx.h" #include iostream using namespace std; int _tmain(int argc, _TCHAR* argv[]) { int NumbHold[5]; int * ptrNumb;
