How do I handle errors with stringstream in C++?

How do I handle errors with stringstream in C++?

In C++, you can check for errors in a stringstream by using the fail() and bad() member functions.

Can you give me an example of how to use those functions?

Sure! Here's a simple example:

#include <sstream>
#include <iostream>

int main() {
    std::stringstream ss;
    int number;
    ss << "abc"; // Invalid input
    ss >> number;

    if (ss.fail()) {
        std::cout << "Error: Invalid input!" << std::endl;
    }
    return 0;
}

What happens if I don't check for errors?

If you don't check for errors, your program may produce unexpected results or crash due to invalid data being processed.

Are there any best practices for using stringstream?

Yes, always validate your input, clear the stringstream after use, and handle exceptions to ensure robust error handling.
