The function gets() reads characters from the stdin and stores them at the provided input buffer. However, gets() will keep reading until it encounters a newline character. Unless the buffer is large enough, or the length of the line being read is known ahead of time, gets() can potentially overflow the input buffer and start overwriting memory it is not supposed to, wreaking havoc or opening security vulnerabilities.

Answer / Alok Gautam

Using `gets()` is dangerous because it doesn't check the buffer size, which can lead to buffer overflows. To safely read input into an array, you can use fgets() function instead, which allows you to specify the maximum number of characters to be read.
