#include <math.h>
main( )
{
cout.precision(3);
cout << sqrt(4) << “\n”;
cout.precision(2);
cout << 2.3456 << “\n”;

class matrix
{ int a[4] [4];
 public :
 // member functions
}
Write a necessary member function to accept and display matrix.
Let m1
 and m2 are two matrices. Find out m3
 = m1
 + m2
 (overload
‘+’ operator).
(e) Design a C++ class contain member function display( ). Write a
program to count number of times display( ) function is called.
(Use static data member)

in ascending order using function overloading.
(d) Write a C++ program to calculate simple interest amount. Use
default value for rate.
(e) Trace output of the following program and explain it.
Assume there is no syntax error :
#include <iostream.h>
Class base
{ public :
virtual void fun( )
{ cout << “function of base”; }
void run( )
{ fun( ); }
};
Class derived : public base
{ public :
