modern C++ for loop, but you still want an index/technologies/code_exchange/b/blog/posts/modern-c-for-loop-but-you-still-want-an-indexC++ has a range loop. A for loop that will run over all elements in the range you give it: std::vector&lt;int&gt; v = {0, 1, 2, 3, 4, 5}; // ... for (auto i : v) std::cout &lt;&lt; i &lt;&lt; &#39; &#39;; std::cout &lt;&lt; &#39;\n&amp;#...en-USTelligent Community 12RE: modern C++ for loop, but you still want an indexhttps://community.element14.com/technologies/code_exchange/b/blog/posts/modern-c-for-loop-but-you-still-want-an-indexFri, 07 Nov 2025 02:58:06 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:9183c041-eb49-4a15-8c01-3757463c53a9Stuart_S1<p>Is the &#39;auto&#39; keyword valid in basic C, I might give it a shot on the old DevCPP</p><img src="https://community.element14.com/aggbug?PostID=29326&AppID=74&AppType=Weblog&ContentType=0" width="1" height="1">RE: modern C++ for loop, but you still want an indexhttps://community.element14.com/technologies/code_exchange/b/blog/posts/modern-c-for-loop-but-you-still-want-an-indexThu, 06 Nov 2025 20:24:13 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:9183c041-eb49-4a15-8c01-3757463c53a9DAB0<p>Nice post Jan.</p><img src="https://community.element14.com/aggbug?PostID=29326&AppID=74&AppType=Weblog&ContentType=0" width="1" height="1">RE: modern C++ for loop, but you still want an indexhttps://community.element14.com/technologies/code_exchange/b/blog/posts/modern-c-for-loop-but-you-still-want-an-indexWed, 05 Nov 2025 21:41:18 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:9183c041-eb49-4a15-8c01-3757463c53a9Jan Cumps0<p>The example in this blog is trivial.
