Hi there,

First you will need to create an object of ifstream to read the file:

1
2
3

#include <fstream>
#include <string>
ifstream ifs;

Then you open the file:

ifs.open("filename");

Then you read every word into a string and check against the search-word:

std::string tmp_word;

while (ifs.good())
{
    ifs >> tmp_word;
    if (tmp_word.compare(search_word) == 0)
    { /* ... */ }
}

Hopefully that will get you on your way.

All the best,
NwN
