I have a problem. I have a function that search a string in a text file. This function return an int: 0 if the string I must be search isn't in the file, 1 otherwise.
The problem is: if the searching string is "input1" and in the file there is a string "counter_input1" the function return 1 instead must be return 0.
Bye

Post your code plz....

when the string is found, check the character immediately before and after to see if it is a space. If not a space, then the string is not what you want.

Good morning!
I have resolved my problem! I have used the strtok function....
Thank you

Sorry, I can not make sense of what is your question or problem.
Could you state it in other words?.
Did you tried the posted code and it didn't work for you? or you are having problems in creating a program that does the same thing?.

Sure. If you would
1) explain what you've tried
2) show what you've tried (read this)
3) not hijack someone else's thread -- make your own

I get a problem with that?
>clrscr();
Why, no need for this or conio.h which is not standard.
Read the following...Looks like you're comparing chars instead of c-style strings.

use fgets() instead of fgetc() and your program will work better and be a lot less complicated.
delete line 5, NULL is defined in standard c header files.
remove the braces on lines 11, 12 and 13. They are not necessary there.

serch string in text file
Adak 419 Nearly a Posting Virtuoso
Welcome to the forum, Akshay1.
This thread is 3 years old - how about starting a new one? More specifics of your assignment, would help. Also, what is stopping you from including string.h and using strstr() to find your string in the text file.?

#include"stdio.h"

void main()

FILE *fp;
char ch, search_string[25], temp[25];
int i=0, k, search_len;
long int count=0;

scanf("%s",search_string);

getch();
exit(0);
}
while((ch=fgetc(fp))!=EOF)
{
if(i<search_len)
{
temp[i]=ch;
++i;
}
if(i==search_len)
{
count++;
temp[i]='\0';
k=stricmp(search_string,temp);
if(k==0)
{
printf("search successful\n");
}
i=0;
fseek(fp,count,SEEK_SET);
}
}
}
this is the easiest way to do it.

I think TextFinding.com may help you. It is a useful and easy tool to search string in a text file
