Read Ascii data file -Qt

Hi Obad,

>>>I have this smaple of data for 12 record from the compleat file which has 41000
I am sorry I could not understand your question good, Can you please explain a bit, Do you mean that You have a data base which is having 41000 records? IS that in some RDBMS or DBMS like oracle or mySql sort of data base,? OR is that simple stored in some text file???
WHat do you mean by " I have sample of Data for 12 Records" ????
please explain

thanks for your responce
I have excel file which  has 41000 row I need to read 10 rows only  i used this code but nothing :

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

int main () {
string line;
ifstream myfile ("example.txt");
if (myfile.is_open())
{
while (! myfile.eof() )
{
getline (myfile,line);
cout << line << endl;
}
myfile.close();
}

else cout << "Unable to open file";

return 0;
}

As I said to you problem in the file location
