Pushing back into 2 dimensional vectors

[penguinyaro]

How do you do it in C++?

This is what I assumed:

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

int main()
{
	ifstream getData;
	vector<string> year;
	vector< vector<string> > title;
	vector< vector<double> > gross;
	vector< vector<string> > lastname;
	vector< vector<string> > firstname;
	vector< vector<int> > age;
	vector< vector<char> > type;
	vector<int> counter(7, 0); // 0 = L, 1 = Y, 2 = T, 3 = G, 4 = A, 5 = Q, 6 = bad input

	int i, j, n;
	string yearin;
	string titlein;
	double grossin;
	string lastnamein, firstnamein;
	int agein;
	char typein;

	bool done = false, done1 = false;
	char input;

	i = 0;
	getData.open("moviescs105.txt");
	while (!done1)
	{
		getData >> yearin;
		if (yearin == "ENDOFFILE")
		{
			done1 = true;
		}
		else 
		{
			year.push_back(yearin);
			getData >> n;
			for (j = 0; j > n; j++)
			{
				getData.ignore(200,'\n');
				getline(getData, titlein);
				title[i].push_back(titlein);
				getData >> grossin;
				gross[i].push_back(grossin);
				getData >> lastnamein;
				lastname[i].push_back(lastnamein);
				getData >> firstnamein;
				firstname[i].push_back(firstnamein);
				getData >> agein;
				age[i].push_back(agein);
				getData >> typein;
				type[i].push_back(typein);
			}
			getData.ignore(200,'\n');
			i++;
		}
	}
	
	getData.close();

pushing back into 1 d vector works fine. But I don't knwo how to do it for 2 dimensional ones. Am I supposed to use an itterator or something? And if so how?

Wouldn't it be easier to have a structure?

typedef struct {
	string year;
	string title;
	double gross;
	string lastname;
	string firstname;
	int age;
	char type;
	int counter; // 0 = L, 1 = Y, 2 = T, 3 = G, 4 = A, 5 = Q, 6 = bad input
} PersonData;

[penguinyaro]

while I imagine that would be worlds easier. I'm not allowed to use structures.

You could just create a new class containing all the necessary fields and instantiate objects from that. Then you could have

vector<myContainer> containerObjects;

Are you allowed OO code?

[penguinyaro]

Probably not on the count of I don't know what you just said.

[Kezzer]

Are you allowed to use Object-Oriented programming? i.e. classes

[DJMaze]

C++ is all about OOP, how the hell could a teacher disallow you to use objects?

[penguinyaro]

It's an intro class. Object oriented is next class up.

Peng, welcome on our boards!
For your question, use the "search" button for 2d array's (or something similar). You'll find easy-to-understand examples, although all the functions are wrapped in a class. But observe the functions (methods we call them) and you'll have nice hints (free giveaways practically).

Like this idea?
Good luck!

I'll check it out. Thanks for your all the help.
