C fputs() and fgets():

The fputs() and fgets() in C programming are used to write and read string from stream. Let’s see examples of writing and reading file using fgets() and fgets() functions.

Writing File : fputs() function

The fputs() function writes a line of characters into file. It outputs string to a stream.

Syntax:

int fputs(const char *s, FILE *stream)

Example:

#include<stdio.h>

#include<conio.h>

void main(){

FILE *fp;

clrscr();

fp=fopen(“myfile2.txt”,“w”);

fputs(“hello c programming”,fp);

fclose(fp);

getch();

}

myfile2.txt

hello c programming

Reading File : fgets() function

The fgets() function reads a line of characters from file. It gets string from a stream.

Syntax:

char* fgets(char *s, int n, FILE *stream)

Example:

#include<stdio.h>

#include<conio.h>

void main(){

FILE *fp;

char text[300];

clrscr();

fp=fopen(“myfile2.txt”,“r”);

printf(“%s”,fgets(text,200,fp));

fclose(fp);

getch();

}

Output:

hello C programming
