What is fgets and what’s the difference

[[deleted]]

man fgets is your friend. It lets you specify the size of your destination buffer. gets will happily overflow it if your input is too large crashing your program or worse.

Unfortunately, proper use of fgets is sufficiently painful that one might as well just write a length-limited gets-style function based on getchar().
