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
