How do I avoid iostream pitfalls in C++?

In C++, using iostream can lead to several common pitfalls, particularly related to performance and formatting. Here are some tips to avoid these issues:

• Use 'std::ios::sync_with_stdio(false)'. This allows you to untie the C++ standard streams from C-style stdio, resulting in faster input/output operations.
• Reserve streams for complex formatting. Keep simple I/O operations to C-style input/output for better performance if you do not need formatting.
• Consider using cin.tie(nullptr). This unties cout from cin, preventing unnecessary flushing of the output buffer.
• Be cautious with locale settings. Frequent changes in locale can lead to performance overhead, so adjust it only when absolutely necessary.

By implementing these strategies, you can mitigate the common pitfalls associated with iostream in your C++ programs.
