help searching words in large files

hello,

i made a simple app that searches a small sized file for example 100 lines, finds a word you want it to find and prints the whole line that has that word

Code:

#include <stdio.h>
#include <string.h>
int main(){
    char a[100];
    FILE *fin=fopen("in.txt","r");
    FILE *fout=fopen("out.txt","w");
    while(fgets(a,sizeof(a),fin)!=NULL){
          if (strstr(a,"someword")){
                 fprintf(fout,"%s\n",a);}
                 }
    fclose(fin);
    fclose(fout);
    return 0;
}

when i try big files, it shows up the "Please tell Microsoft about this problem." error.

i searched but couldnt find anything, would appreciate any help provided.

thanks

Check to make sure the file is actually opening.


Quzah.

indeed the file didnt open

is there any other function or algorithm in order to open such files?

ps: the file is 5.5 mb

Your path is probably wrong. Six megs shouldn't be a problem to open.

Maybe they are joking too.
