fgets is a function in C programming language that reads a string of characters with a specific length from a given file stream source. As far as traceable, fgets stands for file get string. It is included in the C standard library header file stdio.h.

The fgets function terminates reading after a new-line character is found. The length argument includes space needed for the null character which will be appended to the end of the string. As a result, to read N characters, the length specification must be specified as N+1. The string read is returned. The prototype of the function is as follows:

char* fgets(char *string, int length, FILE * stream)

The stream argument specifies from which stream will the string be read from. stdin is commonly used here, for reading from the standard input. Otherwise, a FILE * value returned by the fopen function is used.

Sample usage

The following code reads characters from the console input and prints them out 20 in a line with the puts function until an EOF occurs.

#include 

#define MAX_LEN 20

int main(void)
