{
cout<<M.Length<<"x"<<M.Breadth<<"x";
cout<<M.Height<<endl;
}
void main()
{
MyBox B1={10,15,5}, B2, B3;
++B1.Height;
Dimension(B1);
B3 = B1;
++B3.Length;
B3.Breadth++;
Dimension(B3);
B2 = B3;
B2.Height+=5;
B2.Length--;
Dimension(B2);
}
(e) Find the output of the following program:

void Convert(char Str[],int Len)
{
for (int Count =0; Count<Len; Count++ )
{
if (isupper (Str [Count] ) )
Str[Count]= tolower(Str[Count]);
else if (islower (Str [Count] ) )
Str[Count]= toupper(Str[Count]);
else if (isdigit (Str [Count]))
Str[Count]= Str[Count] + 1;
else Str[Count] = ‘*’;
}
}
void main ()
{
char Text [] = “CBSE Exam 2005”;
int Size=strlen(Text);
Convert(Text,Size);
cout<<Text<<endl;
for (int C = 0,R=Size-l;C<=Size/2; C++,R--)
{
char Temp = Text[C];
Text [C] = Text [R] ;
Text [R] = Temp;
}
cout<<Text<<endl;
