    You can be stuck in an infinite loop if the user types, for example, "forty two". Better use `fgets()` for user input. You can follow `fgets()` with `strtod()`... – pmg Jan 08 '22 at 12:13
  • Begin by reading *strings* (actually full lines) and then attempt to parse it as a number (using e.g. `strtod`). – Some programmer dude Jan 08 '22 at 12:24
  • Follow the approach of using `fgets`, https://stackoverflow.com/q/26583717/14973743 – Anand Sowmithiran Jan 08 '22 at 13:44
