title: Why is scanf/printf faster than cin/cout?
body: <p>I've made some programs and saw that <code>scanf</code> and <code>printf</code> are considerably faster than using <code>cin</code> and <code>cout</code>? Most of my programs clear the execution time limit, mostly 3 seconds or 5 seconds, on online compilers when using <code>scanf</code>/<code>printf</code> which exceeded the limit while using <code>cin</code>/<code>cout</code>.</p>
