Reading input safely is an essential part of C programming. While functions like <\/span>gets()<\/span> exist, they can be dangerous because they don\u2019t check the buffer size. The safer alternative is <\/span>fgets()<\/span>, which allows you to read strings from the user or a file safely.<\/span><\/p>\n

In this tutorial, you\u2019ll learn how <\/span>fgets()<\/span> works, its syntax, examples, and outputs.<\/span><\/p>\n

What is fgets()?<\/h2>\n

fgets()<\/span> is a standard function in <\/span><stdio.h><\/span> used to read lines of text into a string. It stops reading when:<\/span><\/p>\n

    \n
  1. A newline character (<\/span>\\n<\/span>) is encountered.<\/span><\/li>\n
  2. The specified number of characters has been read.<\/span><\/li>\n
  3. The end-of-file (EOF) is reached.<\/span><\/li>\n<\/ol>\n

    Because you can specify the buffer size, it prevents buffer overflow\u2014something <\/span>gets()<\/span> cannot do.<\/span><\/p>\n
