Find the correct identifiers out of the following, which can be used for naming variables, constants or functions in a C++ program:

While, for, Float, new, 2ndName, A%B, Amount2, _Counter

Observe the following program very carefully and write the names of those header files (s), which are essentially needed to compile and execute the following program successfully :

typedef char TEXT[80];
void main()
{
	TEXT Str[] = 'Peace is supreme';
	int Index=0;
	while (Str[Index]!='\0'){
		if (isupper(Str[Index])){
			Str[Index++]='#';
		}
		else{
			Str[Index++]='*';
		}
	}
	puts(Str);
}

Observe the following C++ code very carefully and rewrite it after removing any/all syntactical errors with each correction underlined.

Note: Assume all required header files are already being included in the program.

#Define float Max=70.0;
Void main()
{
	int Speed
	char Stop='N';
	cin>>Speed;
	if Speed>Max
		Stop='Y';
	cout<<Stop<<end;
} 

Write the output of the following C++ program code:
Note: Assume all required header files are already being included in the program.

void Position(int & C1,int C2=3)
{
	C1+=2;
	C2+=Y;
}
void main()
{
	int P1=20, P2=4;
	Position(P1);
	cout<<P1<<','<<P2<<end1;
	Position(P2,P1);
	cout<<P1<<','<<P2<<end1;
}

Write the output of the following C++ program code:
Note: Assume all required header files are already being included in the program.

class Calc
{
	char Grade;
	int Bonus;
public:
	Calc() {Grade='E';Bonus=0;}
	void Down(int G)
	{
		Grade-=G;
	}
	Void Up(int G)
	{
		Grade+=G;
		Bonus++;
	}
	void Show()
	{
		cout<<Grade<<'#'<<Bonus<<end1;
	}
};
void main()
{
	Calc c;
	C.Down(2);
	C.Show();
	C.Up(7);
	C.Show();
	C.Down(2);
	C.Show();
}

Study the following program and select the possible output(s) from the options (i) to (iv) following it. Also, write the maximum and the minimum values that can be assigned to the variable NUM.
Note :
– Assume all required header files are already being included in the program.
– random(n) function generates an integer between 0 and n – 1.

void main()
{
	randomize();
	int NUM;
	NUM=random(3)+2;
	char TEXT[]='ABCDEFGHIJK';
	for (int I=1;I<=NUM; I++)
	{
		for(int J=NUM; J<=7;J++){
			cout<<TEXT[J];
		}
		cout<<end1;
	}
}

What is a copy constructor ? Give a suitable example in C++ to illustrate with its definition within a class and a declaration of an object with the help of it.

Observe the following C++ code and answer the question.

class Traveller
{
	long PNR;
	char TName[20];
public :
	Traveller() //Function 1
	{
		cout<<'Ready'<<end1;
	}
	void Book(long P,char N[])//Function 2
	{
		PNR = P; strcpy(TName, N);
	}
	void Print() //Function 3
	{
		cout<

Fill in the blank statements in Line 1 and Line 2 to execute Function 2 and Function 3 respectively in the following code:

void main()
{
	Traveller T;
 _________ //Line 1
 _________ //Line 2
 }//Stops here 

Observe the following C++ code and answer the question.

class Traveller
{
	long PNR;
	char TName[20];
public :
	Traveller() //Function 1
	{
		cout<<'Ready'<<end1;
	}
	void Book(long P,char N[])//Function 2
	{
		PNR = P; strcpy(TName, N);
	}
	void Print() //Function 3
	{
		cout<<PNR << TName <<end1;
	}
	~Traveller() //Function 4
	{
		cout<<'Booking cancelled!'end1;
	}
};

Which function will be executed at }//Stops here? What is this function referred as?

Write the definition of a class PIC in C++ with the following description :

Private Members
– Pno            //Data member for Picture Number (an integer)
– Category      //Data member for Picture Category (a string)
– Location     //Data member for Exhibition Location (a string)
– FixLocation //A member function to assign
             //Exhibition Location as per category
            //as shown in the following table

Public Members
– Enter()    //A function to allow user to enter values
            //Pno, category and call FixLocation() function
– SeeAll() //A function to display all the data members
