C++: Read from text file and separate into variable

Question

I have this in a text file:

John 20 30 40
mike 30 20 10

How do i read from the text file and separate them into variable name, var1, var2,

Answer 1

Something like this should work (I don't have a compiler handy, so you may need to tweak this a little):

#include 
#include 
using namespace std;


int main()
{
    ifstream inputFile("marks.txt");
    string line;

    while (getline(inputFile, line))
    {
        istringstream ss(line);

        string name;
        int var1, var2, var3;

        ss >> name >> var1 >> var2 >> var3;
    }
}

Edit: Just saw this again, I don’t know why I chose the get line approach earlier. Doesn’t the following (simpler solution) work?

#include 
using namespace std;

int main()
{ 
    ifstream fin(“marks.txt”);

    string name;
    int var1;
    int var2;
    int var3;

    while (fin >> name >> var1 >> var2 >> var3)
    {
        /* do something with name, var1 etc. */
        cout << name << var1 << var2 << var3 << “\n”;
    }
}
