Question

I have read in data from a file and want to store the data as a vector of objects.

vector <Thing*> thingVector;
for (int i = 0; i < 10; i++) {
// Read in contents of file
getline(fileName, v1, ',');
cout << v1 << endl;
getline(fileName, v1, ',');
cout << v2 << endl;
getline(fileName, v3, ',');
cout << v3 << endl;
getline(fileName, v4, '\n');
cout << v4 << endl << endl;
// Store
Thing* thingDetails = new Thing(v1, v2, v3, v4);
thingVector.push_back(thingDetails);
delete thingDetails;
}
thingFile.close();
cout << "Size of THING vector is " << thingVector.size() << endl; // Displays 10

cout << thingVector[0].getV1 << endl; // ERROR HERE

How can I store each record in the vector and then access the data?

I also tried to do it like this:
thingVector.push_back(Thing(v1, v2, v3, v4));

I didn’t have the last and third to last lines in the for statement when I tried it like this, but I couldn’t access the data so gave up on this method.

Any suggestions?

THING .H FILE

#ifndef THING_H
#define THING_H

#include <string>

using namespace std;

class Thing {
public:

Thing(string v1, string v2, string v3, string v4);
string getV1();
string getV2();
string getV3();
string getV4();

private:
string v1;
string v2;
string v3;
string v4;
};

#endif

THING .CPP FILE

#include "thing.h"

#include <string>

using namespace std;
Thing::Thing(string aV1, string aV2, string aV3, string aV4) {
v1 = aV1;
v2 = aV2;
v3 = aV3;
v4 = aV4;
}

string Thing::getV1(){
return v1;
}

string Thing::getV3(){
return v2;
}

string Thing::getV3){
return v3;
}

string Thing::getV4(){
return v4;
}

You should use

vector <Thing> thingVector;
...
thingVector.push_back(*thingDetails);

This will pass object rather than the pointer.

Also

cout << thingVector[0].getV1() << endl; // Convert to a function call.
