Exception Handling

Exception handling in C++ is a mechanism that enables elegant handling of anomalous situations and runtime faults to ensure the program can manage unexpected situations. C++ uses the try, throw and catch keywords to handle exceptions. Code in ‘try’ blocks has the potential to throw exceptions that are raised using `throw` instructions. and ‘catch’ blocks deal with exceptions thrown in the matching ‘try’ block.

Example:

The below example demonstrates the exception handling mechanism using try, throw and catch blocks

C++

// C++ program to demonstrate exception handling

#include <iostream>
#include <stdexcept>
using namespace std;

int main()
{
    try {
        // Declare and initialize two integers.
        int x = 10, y = 0;

        // Check if the divisor is zero.
        if (y == 0)
            // Throw a runtime error exception if divisor is
            // zero.
            throw runtime_error("Divide by zero error");

        // Perform division and print the result (this line
        // won't execute if y is zero).
        cout << "Result: " << x / y << endl;
    }
    catch (const runtime_error& e) {
        // Catch the runtime error exception and print the
        // error message.
        cout << "Exception caught: " << e.what() << endl;
    }

    return 0;
}

Output

Exception caught: Divide by zero error
