Definition and UsageThe fgets() function reads content from the file up to the next line break and writes it into a char array. A \0 null terminating character is appended to the end of the content. The position indicator is moved to the next unread character in the file.The fgets() ...
In this chapter we will learn all the functions used on strings in C - gets(), fgets(), getline(), getdelim(), getchar(), puts(), putchar(), strlen() in C language.
The fgets function reads at most one less than the number of characters specified by n [...] The fgets function returns s if successful. If end-of-file is encountered and no characters have been read into the array, the contents of the array remain unchanged and a null pointer is return...

int c; while ( (c = getchar()) != EOF && c != '\n') { } One way or another, it would be preferable to place it in a static function and leave it to the optimizer to determine whether or not to inline it. Every time you change from using scanf() to fgets() for input,...
