Hi,
I have written a code for removal of stopwords from a string but the problem is I want to remove stopwords from a text file which contains a huge amount of text.I want my code to read the text file line by line and then remove the stopwords from each line. I tried using fstream but I couldnt succeed in doing so.Plz I need help to do so.This is something tht I have done so far.

Thankyou

code snippet

#include <iostream>
#include <string>
using namespace std;

int main ()
{ string arr[3]={" a","an","the"};
string base_str;
size_t i;
int ans=0;
cout<<"\n enter a string::";
getline(cin,base_str);

for(int j=0;j<3;j++)
{
i = base_str.find(arr[j]);
while(i != string::npos)
{
base_str.compare(arr[j]);

base_str.replace(i,arr[j].length(),"");
i = base_str.find(arr[j]);
}
cout<<base_str<<endl;
}

return 0;

}

I'm not a C++ programmer so probably can not help you, but two comments

1) post the code that you have problems with and tell us what the exact problem is
2) use code tags around your code
