I'm currently tackling a coding problem in C++ that involves converting a string to an integer. Here's a simplified version of the code snippet:



Despite my efforts and also trying to search on multiple sites like Scaler, the code seems to encounter unexpected behavior during the conversion. What potential pitfalls might be causing this issue, and how can I modify the code to ensure a successful conversion from string to integer? Additionally, are there alternative approaches or best practices for handling such conversions in C++?

It would be helpful if you told us what the behavior is that you're not expecting.

Indeed, appears to work fine (hit 'Run'): https://onlinegdb.com/ip061XjBE

You mean it behaves unexpectedly with other inputs, and if so, what are those inputs?
