C fputs() and fgets()

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
