How do you search a document for a string in c++?

Question

Here's my code so far:

#include<iostream>
#include<string>
#include<fstream>

using namespace std;

int main()
{
    int count = 0;
    string fileName;
    string keyWord;
    string word;


    cout << "Please make sure the document is in the same file as the program, thank you!" 
         << endl << "Please input document name: " ;
    getline(cin, fileName);
    cout << endl;

    cout << "Please input the word you'd like to search for: " << endl;
    cin >> keyWord;
    cout << endl;
    ifstream infile(fileName.c_str());
    while(infile.is_open())
    {
        getline(cin,word);
        if(word == keyWord)
        {
            cout << word << endl;
            count++;
        }
        if(infile.eof())
        {
            infile.close();
        }

    }
    cout << count;

}

I'm not sure how to go to the next word, currently this infinite loops...any recommendation?

Also...how do I tell it to print out the line that that word was on?

Thanks in advance!

Answer 1

while(infile >> word)
{
    if(word == keyWord)
    {
        cout << word << endl;
        count++;
    }
}

This would do the job. Please read about streams more.
