Give the difference between the Type Casting and automatic Type Conversion. Also, give a suitable C++ code to illustrate both.

Which C++ header file(s) are essentially required to be included to run/execute the following C++ source code (Note: Do not include any header file, which is/are not required);

Void main()
{
	char TEXT[] = 'SomeThing';
	cout<<'Remaining SMS Chars:'
	<<160-strlen(TEXT)<< endl;
}

Rewrite the following program after removing the syntactical error(s) (if any). Underlie each correction.

#include<iostream.h>
Class Item
{
	long IId,Qty;
public:
	void Purchase
	{
		cin>>IId>>Qty;
	}
}	void Sale()
{
	cout<<setw(5)<<IId<<'Old:'<<Qty<<endl;
	cout<<'New:'<<--Qty<< endl;
}
void main()
{
	Item I;
	Purchase();
	I.Sale();
	I.Sale(0)
}

Find the output of the following program:

#include<iostream.h>
class METRO
{
	int Mno, TripNo,PassengerCount;
public:
	METRO (int Tmno=1)
	{
		Mno=Tmno;TripNo=0;PassengerCount=0;
	}
	void Trip(int PC=20)
	{
		TripNo++;PassengerCount+=PC;
	}
	void StatusShow()
	{
		cout<<Mno<<':'<<TripNo<<':'<<PassengerCount<<endl;
	}
};
	void main()
	{
		METRO M(5),T;
		M.Trip();
		T.Trip(50);
		M.StatusShow();
		M.Trip(30);
		T.StatusShow();
		M.StatusShow();
	
	}

Find the output of the following program:

#include<iostream.h>
#include<c.type.h>
typeof char Str80[80];
void main()
{
	char*Notes;
	Str80 Str='vR2GooD':
	int L = 6;
	Notes =Str;
	while(L>=3)
	{
		Str[L]=(isupper(Str[L])?tolower(Str[L]):toupper(Str[L]));
		cout<<Notes<<endl;
		L--;
		Notes++;
	}
}

Observe the following program and find out, which output(s) out of(i) to(iv) will not be expected from the program? What will be the minimum and the maximum value assigned to the variable chance?

#include<iostream.h>
#include<stdlib.h>
void main( )
{
	randomize( );
	int Arr[]={9,6},N;
	int Chance=random(2)+10;
	for (int C=0;C<2;C++)
	{
		N=random(2);
		cout<<Arr[N]+Chance<<'#';
	}
}

What is the difference between the members in private visibility mode and the members in protected visibility mode inside a class? Also, give a suitable C++ code to illustrate both.

Answer the question (i) and (ii) after going through the following class :

class Travel
{
	int PlaceCode; char Place[20]; float Charges; public:
Travel( )	//Function 1
{
	PlaceCode=1;strcpy(Place,'DELHI');Charges=1000;
}
void TravelPlan(float C )	// Function 2
{
	cout<<PlaceCode<<':'<<Place<<':'<<Charges<<endl;
}
~Travel( )	// Function 3
{
	cout<<'Travel Plan Cancelled'<<endl;
}
Travel(int PC,char p[],float C)	// Function 4
{
	PlaceCode=PC;strcpy(Place,P);Charges=c;
}

(i) In Object Oriented Programming, what are Function 1 and Function 4 combined together referred as?

(ii) In Object Oriented Programming, which concept is illustrated by Function 3? When is this function called/invoked?
