Are you an embedded system programmer? Checkout the rank of your favorite programming language according to IEEE Spectrum ranking. C language is in the first place for programming devices controllers, followed by C++, Arduino, then Assembly.
IEEE Spectrum has special methods to figure these ranks, for example they “measure the number of hits for each language by using Google’s API to search for the template (X programming)”, the page states, also using some statistical data from GitHub.
You can review The results in a dynamic way either using the overall ranking by IEEE Spectrum, or by making your own.
