How do I avoid std::endl performance issues?

In C++, using std::endl can cause performance issues due to its behavior of flushing the output buffer every time it is called. This can lead to unnecessary performance overhead, especially in loops. A better alternative is to use the newline character '\n', which allows for more efficient output by not flushing the buffer each time.

Learn how to optimize your C++ output by avoiding std::endl and using newline characters instead. Improve the efficiency of your programs with better output practices.

// Example of avoiding std::endl in a loop for (int i = 0; i < 10; ++i) { std::cout << i << '\n'; // Using '\n' instead of std::endl }
