Using input stream to get string from file.

Basically, I'm trying to open a file that has 10 words/ phrases in it. What I want to do is open the file and pull just one of the phrases out(at random). I'm stuck at this point and am not really sure where to go from here.

Any ideas?

Code:

---


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

using namespace std;

int main ()

{
       
        string random;

        ifstream inFile;
        inFile.open("random.dat");


        inFile >> random;
       
        cout << random << endl;

        inFile.close();


}

Read in all the phrases, then use (say) rand to choose one of them in an unpredictable fashion.

"rand" as in random number generator?

To read in all the phrases do I have to declare them as strings? Then read them in or can I just read them in?

That is the data type that deals with bunches of characters in one glob, yes.

I'm going to take a guess and say "yes".

if you know that there are 10 lines in file - use rand to generate random number and read only required number of lines... (why to read and store all 10 lines if you know you need line number 2)

How do I read in a certain line?

not certain line, certain number of lines, storing only the last
