need help to store coordinates in vector array

[hayatihamid]

i've been trying to store a coordinate in a vector array, and reading the coordinates from a .txt file.

there was no error, but the size of the vector is still 0 (i'm sure there was no value in the vector array)

here's my code:

#include <stdafx>
#include<iostream>
#include<fstream>
#include <stdio>
#include <vector>

using namespace std;

int main() {

ifstream myReadFile;
myReadFile.open("input test.txt");

vector<double> xVal,yVal;
int vectorSize = (int)xVal.size();

double x,y;

while (!myReadFile.eof()) {


myReadFile>>x>>y;
xVal.push_back(x);
yVal.push_back(y);

}
cout<<vectorSize<<endl;

myReadFile.close();
return 0;

}

any guide from the experts?

Looks as if you may not have updated "vectorSize" after loading the file, so you are reporting the size of the vector before populating it.

while (!myReadFile.eof()) {


myReadFile>>x>>y;
xVal.push_back(x);
yVal.push_back(y);

}
cout<<xVal.size()<<endl; // try this

myReadFile.close();
