Exception Handling (try n catch)

Exception handling in C++ is implemented by using try,catch and throw. An example of how these are used is given in the following program : 

try { ....  } // tries a set of statement to test the presence of an exception

throw(VALUE); // to throw a value in case an exception has occured 

catch( ... ) { ... } // to catch the exception and take appropriate steps to handle it. Can have parameters to receive a particular type of value.

// Program for exeception handling in C++

#include <iostream>

int main()
{
    int x;
    std::cout<<" Enter the value of x : ";
    std::cin>>x; // prompts the user to enter some value of x
    try // try block to test the value of x
    {
       if ( x > 0 )
          throw (0); // throws an integer
       else
          throw ('a'); // throws a character
    }
   
    catch(int n)
    {
              std::cout<<" \n Caught Integer !!! ";
    }
    catch(char ch)
    {
               std::cout<<"\n Caught Character !!!";
    }
    std::cin.get();
    return 0;
} // end of main

Exception handled when x < 0

Exception handled when x > 0
