**`fgets()`** is a standard C library function that is used to read a string of characters from a file at the location indicated by the file pointer. Below is the declaration of the `fgets()` function:
```C
char *fgets (char * str,int size, FILE * stream);
```
# Return value
if the read operation from the file is successful, the `fgets()` function return the string that is read.
#key# ﻿EOF: ﻿End-of-File #key# is returned if there is an error ﻿when reading from the file.
# Parameters of the `fgets()` function
* `str`: Pointer to the character array to store the string read from the file.
* `size`: Maximum number of characters that can be read from the file.
* `stream`: Pointer to the file from which the character is to be read.

# Example
Consider the code snippet below, which uses `fgets()` to read the content of a file:

#include <stdio.h>

int main() {

  FILE * fPointer;
  char str[100];

  fPointer = fopen ("fgetsExample.txt", "r");//opening file
  
  while( !feof(fPointer) )//checking EOF
  {
    fgets(str, 100, fPointer);

    if(str!=NULL)//if EOF returned
    {
      printf("%s",str);
    }
  
  }

  fclose(fPointer);
  
  return 0;
}

The `fgets()` function is used in line 12, which reads and subsequently prints the content of the file `fgetsExample.txt` on the screen.
