(iii) case
(iv) Object
(v) struct
(vi) sub
(vii) float
(viii) My_class
(b) Write the names of the correct header files, which must be included in the following C++ code to compile the code successfully :
void main()
{
int X = random(10);
int Y = random(20);
cout<<"sum of "<<X<<" and "<<Y<<" = "<<X+Y<<endl;
}
(c) Rewrite the following C++ program after removing any/all
syntactical errors with each correction underlined :
Note : Assume all required header files are already included in the
program.
void main()
{
cout<<"Enter two integers";
cin>>A>>B;
if A <= B
A += B;
B –= 5;
else
{
B = B + A;
A – 5 = A;
}
cout<<A<<" : "<< B << Endl;
}
 
(d) Find and write the output of the following C++ program code :
 
Note : Assume all required header files are already included in the program.
void ChangeVal(int *M, int N)
{
for(int i=0;i<N ; i++)
{
if (*M%5 == 0)
*M /= 5;
if (*M%3 == 0)
*M /= 3;
M++;
}
}
void main()
{
int Val[]={25,8,75,12};
ChangeVal(Val,4);
for(int i=0;i<4; i++)
cout<<Val[i]<<"*";
cout<<endl;
}
(e) Find and write the output of the following C++ program code :
 
Note : Assume all required header files are already included in the program.
struct Product
{
int X, Y;
};
void Change(Product &P)
{
P.X += 5; P.Y –= 5;
}
void Multiply(int P1, int P2)
{
cout<<"First = "<<P1<<" & Second = "<<P2<<endl;
cout<<"Product = "<<P1*P2<<endl;
}
void main()
{
Product P[] = {{7,10},{10,7},{7,7}};
for(int i=0; i<3; i++)
{
Change(P[i]);
Multiply(P[i].X, P[i].Y);
}
}
