Simple C++ Program for Catch All or Default Exception Handling

Definition

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

Example Program

/*## Simple C++ Program for Catch All or Default Exception Handling */
/*## Exception Handling C++ Programs, Exception Handling Programming*/

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

using namespace std;

int main() {
   int var = 0;

   cout << "Simple C++ Program for Catch All or Default Exception Handling\n";
   // try block - for exception code
   try {
      // Inside try block
      if (var == 0) {
         throw var;
         // Skip all code after throw
      }
   }   // catch block
   catch (float ex) {
      // Code executed when exception Catch with float type
      cout << "Float Exception catch : Value :" << ex;
   } catch (...) {
      // Code executed when exception Catch : for default
      cout << "Default Exception Catch";
   }
   getch();
   return 0;
}

Default Exception Catch

How It Works

This C++ program demonstrates Simple Program for Catch All or Default Exception Handling. 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.
