Need help reading from .txt file!!

[jlatorre80]

Ok, well I am new to c++ and have been trying to get the basics down. I have a class assingment which require me to read numbers from a file and store them into a vector as long int. An example of the file would be :

19531029L
20081104L
19770615L
19300723L

I started and got it compiled, but only got 1 number and the rest 0. So I did research and found out i might have to change it to a string first and then back to long int. but i'm having a hard time figuring it out. I have posted my code, which does have some things that might not belong in comments right now, but i had to test it. If someone has a better idea and can explain why im having a hard time changing string to long int, please advise me

#include <iostream>
#include <fstream>
#include <vector>
#include <string>
using namespace std;

int main(){
    char temp[100];
    char line;
    long int x;
    long int num;
    int y=0;
    vector<long int> dateList(11);

    ifstream inFile;
    inFile.open("C:\\inputdata.txt");

    /*if (!inFile) {
        cerr << "Unable to open file datafile.txt";
        exit(1);   // call system to stop
    }
    */

    while(inFile >> x){
        getline(inFile>>x,);
        //i=strtol(temp,0,10);
        num = atoi(line);
        //num = strtol(line,0,11);
        dateList[y] = num;
    }

    for (int i=0; i < dateList.size(); i++)
        cout << dateList[i] << " ";

    inFile.close();

    cin >> x;
    return 0;

}

stdlib's atol() not atoi().

int countlines;
while(!inFile.eof())
{
inFile.getline(temp, 100);
alongarray[countlines] = atol(temp);
countlines += 1;
}

Good enough.

What kind of variable would "temp" be?? And is there a way to get it directly to the vector i have declared?

Just assign the long value the way you normally would.
temp is the the "char temp[100];" you had...

You also want to check if the file was actually opened too:

if(inFile.is_open())
{
/*file handling code*/
inFile.close();
}
else
{
/*error handling*/
}
