Hello,
okay here is what I am trying to do.
in my program I open up a file and use the while(getline(input,word))
loop go through the text file. After I have gone through the entire file I close it. Now, I would like to go through the file again in the same function, but when I attempt to use the loop again, I am not able to. Now I am not sure why, I am guessing the reason is because I am now at the end of the file, but I am not certain.

I know there is a command that says that I open a file and start at the end. Is there possible a command that makes me start at the beginning?

std::ios::ate

std::ios::???


Thanks,
Ronald

Here is some example code.
The file contains
Cat
Dog

that is it. Now when I execute it. It will print out:
Cat
Dog

and that is it. It should print go:
Cat
Dog
Cat
Dog

any thoughts?

#include <iostream>
#include <stdlib.h>
#include <fstream>
using namespace std;
#include <string>
#include "time.h"
#include <vector>
#include <algorithm>
#include <sstream>

int main()
{
string calcstring;
ifstream input1;
input1.open("calc.txt",ios:ut);
while (getline(input1,calcstring))
cout<<calcstring<<endl;
input1.close();
input1.open("calc.txt",ios:ut);
while (getline(input1,calcstring))
cout<<calcstring<<endl;
input1.close();


return 0;
}


Thanks for the help
Sincerely,
Ronald

I found it. You call this right after the first time you do input.close();

input1.clear(); // Call clear() to clear the fail() flag before reopening
