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)
}

#include<iostream.h>
#include<iomanip.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;
       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++;
	}
}
