File content -> string?

Is there a way to get the contents of a file and place it into a string?
So far I have the following:

Code:

---

#include <cstdlib>
#include <iostream>
#include <fstream>
#include <string>
#include <map>

using namespace std;

int main()
{
    ifstream file;
    string word;
    int count;
    map<string, int> table;
    file.open("main.cpp");
    if(!file)
    {
        return 1;
    }
    word = "#include";

    system("PAUSE");
    return EXIT_SUCCESS;
}

---

I've tried setting word = file, doing a while(file>>word), and some other things (such as setting word = file.open(), file.count, and things that generally didn't work).
Is there a way to set the contents from that file into the string for manipulation?

try somethign along these lines:

Code:

---

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

int main()
{
    std::string word;
    std::fstream file("Untitled1.dat",std::ios::in);
    getline(file,word,static_cast<char>(0x3));
    std::cout<<word;
    std::cin.get();
    return 0;
}

---

in case you're wondering, 0x3 is the hex value for ETX, or End of Text. I don't know how reliable it is, but it worked in the case I tried it in.

THANK YOU!
Now why can't google pop up with stuff like this? ><

read the first hit, second block of example code: http://www.google.com/search?num=100...2B&btnG=Search

:D

Figures I would search for the wrong thing...

Anyway, I hate to be a bother but is there any speacific reason why "no" always returns as 0?

Code:

---

#include <cstdlib>
#include <iostream>
#include <fstream>
#include <string>
#include <map>
#include <algorithm>
#include <vector>

using namespace std;

int main()
{
    string search = "#include";
    std::string word;
    vector<string> vs;
    //int no= 0;
    std::fstream file("main.cpp",std::ios::in);
    while(getline(file,word,static_cast<char>(0x3)))
    {
        vs.push_back(word);
    }
    int no = count(vs.begin(),vs.end(),search);
    cout<<word;
    cout<<no;
    std::cin.get();
    return EXIT_SUCCESS;
}

As far as I can tell I'm using the count() functions correctly, and there is obviously more than 0 #includes in the string...

Bleh ><

getline() reads in a line up to a newline, not just any white space, so vs[0] would be "#include <cstdlib>" instead of just "#include". I suggest using the >> operator rather than getline(). Alternatively, you could use a function search through the strings for "#include".

I'm sorry, joshdick, but I'm not sure what you are saying to do. Could you "dumb" it down a bit?


EDIT: I managed to get it to work on a per line basis, but I can't find a way to search for a substring (so I can search for include instead of #include....)

If you have code like
getline(cin, name);
and I enter "John Q. Public" and hit enter
then name == "John Q. Public".
But if instead you have code link
cin >> name;
and I enter "John Q. Public" and hit enter,
only "John" will be stored in name.

getline() keeps reading in until a newline (or EOF) is reached.
cin >> name; only reads up to whitespace.

If you'd prefer to store one word at a time without whitespace, use cin >>. If you want to store an entire line with spaces and tabs and such in it, then use getline(). I think for your purposes it'd be better to do the former.

Code:

---

string a = "Hello, World!";
cout << a.find("lo");

---

This will output 3 because that is the index of the substring "lo" in a.

Meh...works good enough (the number of includes was just something I wanted to add...), just wish I could get it to stop right before "using"...

Code:

---

#include <cstdlib>
#include <iostream>
#include <fstream>
#include <string>
#include <map>
#include <algorithm>
#include <vector>

using namespace std;

int main()
{
    string search = "using";
    std::string word;
    vector<string> vs;
    int no= 0;
    std::fstream file("main.cpp",std::ios::in);
    while(getline(file,word,'{'))
    {
        vs.push_back(word);
    }
    cout<<"Showing all includes, using namespaces, and arguments of main"<<'\n';
    cout<<vs[0]<<"\n";
    std::cin.get();
    return EXIT_SUCCESS;
}
