Can you explain the try-catch mechanism in C++?

Can you explain the try-catch mechanism in C++?

Sure! The try-catch mechanism in C++ is used to handle exceptions. You wrap the code that might throw an exception in a try block, and if an exception occurs, it is caught in the catch block.

Can you give me a simple code example?

Of course! Here's a simple example:

#include <iostream>
using namespace std;

int main() {
    try {
        int a = 5;
        int b = 0;
        if (b == 0) throw "Division by zero!";
        cout << a / b;
    } catch (const char* msg) {
        cerr << "Error: " << msg << endl;
    }
    return 0;
}

What happens if I don't use try-catch?

If you don't use try-catch, the program will terminate when an exception occurs, and you won't be able to handle the error gracefully.

Are there different types of exceptions in C++?

Yes, C++ has standard exceptions like std::runtime_error, std::out_of_range, and you can also create your own custom exceptions.
