Exception Handling

Exception handling is a crucial aspect of programming, as it allows us to handle errors and unexpected situations that may occur during program execution.

In C++, exception handling is achieved through the use of try and catch blocks. The try block contains the code that might throw an exception, while the catch block is used to handle the exception.

Here is an example of exception handling in C++:

1#include <iostream>
2using namespace std;
3
4int main() {
5    try {
6        // Code that might throw an exception
7    }
8    catch (exception& e) {
9        // Handler for specific exception type 'exception'
10    }
11    catch (...) {
12        // Handler for all other exceptions
13    }
14    return 0;
15}

In this example, the code inside the try block is executed, and if any exception is thrown, it is caught by the appropriate catch block. The first catch block handles exceptions of type exception, and the second catch block handles all other exceptions.

Exception handling allows us to gracefully handle errors and take appropriate actions, such as displaying an error message, logging the error, or performing recovery operations.

#include <iostream>

using namespace std;

​

int main() {

    try {

        // Code that might throw an exception

    }

    catch (exception& e) {

        // Handler for specific exception type 'exception'

    }

    catch (...) {

        // Handler for all other exceptions

    }

    return 0;
