Program Code – Real-Time C++ Programming: Handling Exceptions and Faults

#include <iostream>
#include <exception>

// Define a custom exception class that inherits from std::exception
class NetworkException : public std::exception {
    // Override what() to return a custom message
    const char* what() const throw() {
        return 'Network communication failed';

// Simulate a network operation that may throw a NetworkException
void simulateNetworkOperation() {
    // This is where you'd have your actual network code.
    // We'll just simulate an error for this example.
    throw NetworkException();

// Entry point for the program
int main() {
    try {
        std::cout << 'Attempting network operation...' << std::endl;
    catch (NetworkException& e) {
        // Catch our custom exception and print the error message
        std::cerr << 'Caught an exception: ' << e.what() << std::endl;
        std::cerr << 'Performing cleanup operations...' << std::endl;
        // Perform necessary cleanup and error recovery here
    catch (...) {
        // Catch all other exceptions
        std::cerr << 'An unexpected exception occurred' << std::endl;
    std::cout << 'Program execution continues here...' << std::endl;

    return 0;

Code Output:

Attempting network operation...
Caught an exception: Network communication failed
Performing cleanup operations...
Program execution continues here...

Code Explanation:

The code snippet above demonstrates exception handling in real-time C++ programming. The logic is straightforward yet essential for robust software design, particularly in scenarios involving network communications where exceptions are rather common.

First, a custom exception class NetworkException is derived from the standard std::exception class. This allows for more specific exception handling, tailored to network-related errors. The what() method is overridden to provide a custom error message.

simulateNetworkOperation() function is our hypothetical network operation that, in reality, should contain the actual network handling code. Here, it simply throws a NetworkException to simulate an error condition.

The main() function is the starting point for program execution. It attempts to perform the network operation inside a try block, which is critical because it allows us to define corresponding catch handlers for exceptions that could be thrown.

We have two catch blocks following the try. The first catch block is specifically for NetworkException and will execute if simulateNetworkOperation() throws a NetworkException. It prints out the custom error message and simulates cleanup operations by outputting another message.

The second catch block is a catch-all handler designed to catch any other types of exceptions that are not explicitly handled by the previous catch. This ensures that the program can deal with unexpected exceptions gracefully.

Finally, regardless of whether an exception was caught or not, the program prints a message indicating that the normal flow of the program continues, demonstrating that the exception has been handled and the program has recovered from the error.
