When will you make a function inline and why?

Identify the error(s) in the following code fragment:

int x = 5;

int y = 3;

class Outer {

public:

int x;

int a;

static int s;

class Inner {

public:

void f(int i)

{

x = i;

s = i;

y = i;

a = i;

}

};

// Inner defination over

Inner I1; //Inner object

void g(it i)

{

x = i;

y = i;

a = i;

s = i;

}

 }; 

//outer definition over

Outer Ob1; // outer object int main()

{

Ob1.I1.f(3);//statement1

Ob1.g(8); //statement2

return 0;

}

What will be the values of ::x, ::y, Outer::x, Outer::a, Outer::s, Inner::a after statement 1 and statement 2 of above code?

Rewrite the following C⁺⁺ code after removing the syntax error(s) (if any). Underline each correction.

include<iostream.h>

class FLIGHT{

 long FlightCode;

 char Description[25];

 public:

void AddInfo ()

{

cin>>FlightCode; gets(Description);

}

void ShowInfo()

{

cout<<FlightCode<<“:” <<Description<<end1;

}

};

void main() {

FLIGHT F; 

AddInfo.F();

 ShowInfo.F();

}

Identify the error(s) in the following code fragment:

class X {

int a b;

void count(void)

{

a⁺⁺;

}

public:

int x;

void init(int,int,int);

void print(void);

};

void X::init(int i,int j,int k)  {

a = i;

b = j;

x = k;

}

void X::print(void)

{

count();

cout<<“a=”<<a;<<“b=”

 <<b<<“x=”<<x<<“\”;

}

void func(void);

X Ob1;

int main() {

X Ob2;

Ob1.init(0,1,2);

Ob2.init(2,3,4);

Ob1.print();

Ob2.print();

Ob1.count();

Ob2.count();

}

void func(void)

X Ob3;

Ob1.init(4,5,6);

Ob2.init(7,8,9);

Ob3.init(9,10,11);

Ob3.a = Ob3.b = Ob3.x;

Ob1.count();

Ob2.count();

Ob3.count();

Ob1.print();

Ob2.print();

Ob3.print();

}

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

 public:

Employee()  {}

void Joining()

{

cin>>EmpId; gets(EName);

}

void List ()

{

cout<<EmpId<<“:”

 <<EName<<end1;

void main() {

Employee E;

Joining.E ();

E.List () ;

}
