gets()
The gets() function takes a line from stdin and puts it in the buffer. All characters do into the buffer up to but not including the initial new-line character (\n) or the end-of-file (EOF). If a new-line character is read, the gets() function replaces it with a null character (\0) before returning the line.
Syntax
gets(variable name );
Code
#include<stdio.h>
int main()
{
char string[15];
printf("Kindly Input the text : ");
gets(string);
printf("\n%s",string);
return 0;
}
Output
Kindly Input the text : Hello world
Hello world

How fgets() and gets() compare to each other?
gets() and fgets() are C functions that accept a string with spaces between characters as input. The issue with gets() is that it has a buffer overflow, which means it takes more input than it should. fgets is used to solve this problem ().
The difficulty with the most widely used scanf() function is that it cannot accept spaces in a string's input. When we take a string in a buffer for standard input or a file, we use the gets() and fgets() functions.

Frequently Asked Questions
What isDifference between fgets() and gets() in C?
When a function gets() reads the input from standard input, it converts the newline ('\n') to the null character ('\0'). On the other hand, when function fgets() reads a newline ('\n') character from the file, it doesn't convert it into a null character ('\0'). It is retained as it is.
Which is safe fgets() and gets() in C?
Compared to gets, fgets is safer to use because it checks for character array str limits. Till a newline character is met, gets continues to read characters from the users.
What does the fgets () function do?
To read a string from a file, use fgets(). It accepts three input arguments and stores them in a null-terminated array.
What does the gets () function do?
The gets() function takes a line from stdin and puts it in the buffer. All characters do into the buffer up to but not including the initial newline character (\n) or the end-of-file (EOF).
How many arguments does fgets() take?
It accepts three input arguments and stores them in a null-terminated array. Regarding arguments, the first is the storage array in which we want our string to be stored.
