1. Write a C++ program on simple try-catch mechanism.

 open  Online C++ Compiler and enter below source code

#include <iostream>

using namespace std;

int main ()

 {

   int a,b,x ;

    cout << " enter values of a and b \n ";

 cin >> a;

 cin >> b;

  x=a-b;

    try 

   {

       if( x != 0 )

       {

        cout <<" Result  a/x =" << a/x;

        }

        else

        {

            throw (x);

        }    

   }

   catch(int y)

   {

       cout << " Exception caught x= " << x << endl;

   }

     cout << "\n  end";

   return 0;

}

output 1:

enter values of a and b 

 12

 6

 Result  a/x =2

  end

output 2:

enter values of a and b 

 10

 10

 Exception caught x= 0

  end
