/*

Fgets is normally necessary to read the line of data that is given 
in the majority of circumstances. When bounds checking is done, 
Fgets is a superior choice as well as a better performance, 
allowing the assessment technique.

The term “fgets” usually refers to a type of C library function. Since its
introduction, the use of Fgets has spread to other libraries. Fgets has a lot 
of potentials when it comes to reading any file. The file must, however, be open.
