Simple C++ Program for Rethrowing Exception Handling in Function

Definition

In C++, Exception handling is the special process of reacting to the appearance, while computation.

Example Program

/*## Simple C++ Program for Rethrowing Exception Handling in Function*/
/*## Exception Handling C++ Programs, Exception Handling Programming*/

// Header Files
#include <iostream>
#include<conio.h>

using namespace std;

// Function for Exception Thrown

void exceptionFunction() {
   // try block - inside Function
   try {
      //throw exception : In function
      throw 0;
   } catch (int i) {
      cout << "\nIn Function : Wrong Input :" << i;
      //re throw exception : out of the function
      throw;
   }
}

int main() {
   int var = 0;

   cout << "Simple C++ Program for Rethrowing Exception Handling : In Function\n";
   // try block - for exception code
   try {
      // Inside try block
      exceptionFunction();
   }// catch block
   catch (int ex) {
      // Code executed when exception caught
      cout << "\nIn Main : Wrong Input :" << ex;
   }

   getch();
   return 0;
}

Sample Output

Simple C++ Program for Rethrowing Exception Handling : In Function

In Function : Wrong Input :0
In Main : Wrong Input :0

How It Works

This C++ program demonstrates Simple Program for Rethrowing Exception Handling in Function. It first prepares the data it needs, then uses conditional logic to decide the result, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Use conditional statements to handle the different cases.
3. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
