I am trying to step through code in emacs and am looking for a plugin which will displa the contents of an element when I hover over it. Is there any plugin like this currently? How do you step through code with emacs?

    See the gdb-tag you added. M-x gdb is one tool for debugging C/C++. There is also the realgud project. – Tobias Aug 2 '19 at 3:29
  • You can also do M-x gdb-many-windows(after doing M-x gdb) to see things like locals, threads, breakpoints, etc. There is also great toolbar to do various jumps in a debugger. – Compro Prasad Aug 2 '19 at 14:59
  • There's also gud-gdb, which provides a nice interface for GDB that nicely integrates with GNU Emacs. – user12563 Aug 2 '19 at 15:09
