Program for Swapping the Two Integers
For example, Swapping the two value
int x=4,y=6,t;
t=x;
x=y;
y=t;
Similarly,
void Rolodex::insertAfterCurrent(const std::string& str)
{
RolodexItem* t = current->next;
t->prev = current->next = new RolodexItem ();
current->next->prev = current;
current->next->next = t;
current->next->value = str;
current = current->next;
}
t = current->next
set the next position of the pointer
t->prev= new RolodexItem ();
Initiate the previous position into RolodexItem Object
current->next->next = t;
Set the next of current Next RolodexItem Object into t
Here, t (temporary) is used to change the position of the RolodexItem Object
