Exception Handling in C++

C++ Exceptions

When executing C++ code, different errors can occur: 

• coding errors made by the programmer
• errors due to wrong input.
• The technical term for this is: C++ will throw an exception (throw an error).

C++ try throw and catch

It consist of three keywords: try, throw and catch:

The try statement allows you to define a block of code to be tested for errors while it is being executed.

The throw keyword throws an exception when a problem is detected, 

The catch statement allows you to define a block of code to be executed, if an error occurs in the try block.

The try, throw and catch keywords can not run in Turboc++ it can run on other software's available such as Dev c++

#include<iostream>

using namespace std;

int main()

 {

   int a,b;

   try

    {

     cout<<"enter a and b value:";

     cin>>a>>b;

     if (b == 0)

        throw (0);

     else

cout << "division is :"<<a/b;

    }

   catch (int x)

    {

    cout << "Division not possible ";

    }

  return 0;

}
