- The debate over the best loop style in C++ led to the creation of Compiler Explorer in 2011.
- Different loop styles like for(), while(), range-for, and STL algorithms often compile to identical optimized assembly code.
- Range-for and pointer-based loops produce the same efficient code, avoiding unnecessary size calculations.
- Using standard algorithms or range-for is recommended for clarity, as compilers canonicalize them into optimal underlying patterns.
- The ordinal-based loop style may incur minor inefficiencies, but modern compilers generally optimize well.
