`for(;;)` vs. `while(true)`: Which is Better for Infinite Loops?

Why Use "for (;;)" Over "while (true)" in Infinite Loops?

While both "for (;;)" and "while (true)" accomplish the same task of creating an infinite loop, programmers may choose one over the other for various reasons that extend beyond speed optimization.

1. Tradition and Common Practice:

"for (;;)" has been a common way to define infinite loops in the C programming language since its inception. It has become a customary practice that многие programmers have adopted.

2. Syntax Preference:

Some programmers may simply prefer the syntax of "for (;;)". It concisely states the loop execution condition without the need for a separate loop condition statement.

3. Code Reusability:

If you define "while (true)" as a macro for "for (;;)", as suggested in the question, it limits your ability to use the "while" keyword for other purposes. Separately defining the two constructions (e.g., using preprocessor directives) allows for greater flexibility in code.

4. It's Not Faster:

Contrary to the belief that "for (;;)" is inherently faster, it doesn't actually offer any performance advantage over "while (true)". Both constructs generate equivalent assembly code.

Conclusion:

The choice between "for (;;)" and "while (true)" boils down to personal preference and familiarity. Optimizing infinite loops for speed should not be a consideration, as neither construct offers any measurable difference. Focus on writing clear and maintainable code that best suits your needs.
