My today's CS201 Paper 22-07-2011

Suppose there is class A having data member 'x', 'y' and an object of class B. The class
B has data members 'z'. Write the constructor of a class A that initializes the data
members of class A and class B (using member initializing list). [2]
How can we declare and initialize static data members of a class? [2]
Write down the general syntax for a function that returns a reference? [2]
Differentiate between single-dimensional and multi-dimensional array? [2]
How many arguments does binary member operator function binary non-member
operator function take? [3]
What is an alternative of setw manipulator? [3]
Find the error in the given code [3]

for (int i=0; i<numRows; i++)

{
         for (int j=0; j<numCols; j++)

            }
                  elements[i,j] =m.elements [i][j];

            }
}

Determine the output of following code segment. [3]
x=5;
Switch (x)
{
    case 5;
    cout<<Value is 5;
    case 4;
    cout<<Value is 4;
    break;
}

What is meant by the lifetime of a variable and what is the lifetime of an automatic
variable? [5]
Write a short note on files and also explain how they are handled in C++? [5]

Find the error [5]

class Data
{
private:
const in data;
public:
Data( )
{
cout<<"Constructor Call…\n"; }

void getIncreament( )
{
Cout<<"Data = " <<++data;
}
};

void main( )
{
char*String ;
String= New char[15];
String="Welcome to VU";
cout<<String;
free (String);
}
