Farai Mugaviri e73ffaf2fe Add void pointer to index.md (#22248) ...

* Update index.md

I added void pointers, which can be very useful in C programming, especially when dealing with unknown data types but had not been included.

* fixed formatting issues, removed attributions, moved placement to more appropriate location

* adjusted section header size
