QUESTION: Here is the code:

#include<stdio.h>
#include<string.h>
#include<stdlib.h>

FILE*fp;

void wrfile1();

void main(){

  wrfile1();

}

void wrfile1(){

  char word[10];

  fp=fopen("c:\\text","w");

  while(!feof(fp)){

     fscanf(fp,"%s",word);

     printf("%s",word);

  }
  printf("\n");

  fclose(fp);

}

ANSWER: hi Good Morning!
 nothing wrong with your code , you must have opened your file in "r" read mode instead of "w" mode.

Here is your code with minor modification!
#include<stdio.h>
#include<string.h>
#include<stdlib.h>

FILE*fp;

void wrfile1();

void main(){

wrfile1();

}

void wrfile1(){

char word[10];

fp=fopen("c:\\temp\\text","r");

while(!feof(fp)){

fscanf(fp,"%s",word);

printf("%s",word);

}
printf("\n");

fclose(fp);

}


Option 2:
I ve programmed the same programme using the getc() function check out this code as well.

#include<stdio.h>
#include<string.h>
#include<stdlib.h>

FILE*fp;

void wrfile1();
void main(){
wrfile1();
}

void wrfile1()
{
char ch;
fp=fopen("c:\\temp\\text","r");
while((ch =getc(fp))!= EOF)
  printf("%c" , ch);
fclose(fp);

}


Note: Both programme assumes that the file 'text' is non-empty and existing!

get back to me in case of issues.

Thanks and Regards!

Hi dear bita !

 Sorry for the delay in responding you , since i was busy for the last couple of day's i couldn't respond you !! hum .. am not pretty clear with your ques.

Do you wanna prog that create its own file and read contents from the same ? if so check out the programme given below

#include<stdio.h>
#include<string.h>
#include<stdlib.h>

FILE*fp;

void wrfile1();
void WriteFile();

void WriteFile()
{
  FILE * fp = fopen("c:\\temp\\text","w");

  fprintf(fp,"%s","this is a sample string ");
  fclose(fp);
}


void main(){
WriteFile();
wrfile1();

}

void wrfile1(){

char ch;
fp=fopen("c:\\temp\\text","r");
while((ch =getc(fp))!= EOF)
  printf("%c" , ch);


fclose(fp);

}
