CPP program to rethrow an exception

In this article we will learn to implement a CPP program to rethrow an exception. A C++ program is provided below to demonstrate rethrowing an exception.

Program is as follows:

#include <iostream>
using namespace std;
int main()
{
	try
	{
		int a, b;
		cout<<"Enter two integer values: ";
		cin>>a>>b;
		try
		{
			if(b == 0)
			{
				throw b;
			}
			else
			{
				cout<<(a/b);
			}
		}
		catch(...)
		{
			throw; //rethrowing the exception
		}
	}
	catch(int)
	{
		cout<<"Second value cannot be zero";
	}
	return 0;
}

Input and output for the above program are as follows:

Enter two integer values: 10 0
Second value cannot be zero
