cout or printf which of the two has a faster execution speed C++?
<p>I have been coding in C++ for a long time. I always wondered which has a faster execution speed <code>printf</code> or <code>cout</code>?</p>

<p>Situation: I am designing an application in C++ and I have certain constraints such as time limit for execution. My application has loads printing commands on the console. So which one would be preferable <code>printf</code> or <code>cout</code>?</p>
