c++ arrays and file reading question

[prestonprice57]

I am doing a project and I have to read from a file and input the values into an array. I know how to do this. But now we have to read from a file in put it in multiple arrays. The file that I'm reading looks like this:

4
Assign1 200 95
Assign2 100 80
Project 100 -1
Midterm 100 -1

How would I make it so that the names are put into one array, the 1st numbers in another, and the last numbers in another array?

int readFile(char fileName[])
{
  int i = 0;
  ifstream input;

  input.open(fileName);

  while (i != input.eof())
    {
      input >> grade[i];
      i++;
    }
  input.close();
}

How do I make it so that there are 3 seperate arrays stored instead of just the one grades array

Sense there is a space, use getline. You can tell it to stop reading at a space so

getline(input, grade[i], ' ');

or am I dead wrong?

edit: just tested it, the getline will work just tell it to stop reading at a space.

so

getline(input, grade[i], ' ');
getline(input, score[i], ' ');
getline (input, points[i], '\n'); // or w/e you want the arrays called..

#include <iostream>
#include <string>
#include <sstream>
#include <fstream>
#include <cstdlib>

void print(std::string sa[], int len) {
	for (int i = 0; i < len; ++i)
		std::cout << sa[i] << ' ';
	std::cout << '\n';
}

int main() {
	using namespace std;

	ifstream fin("data.txt");

	if (!fin) {
		cerr << "Open file data.txt failed!\n";
		return 1;
	}

	char lines[12] = "";
	fin.getline(lines, sizeof(lines));
	int lineCount = atoi(lines);

	// The better way is using vector<string> rather than string arrays.
	string* cols1 = new string[lineCount];
	string* cols2 = new string[lineCount];
	string* cols3 = new string[lineCount];

	istringstream iss;
	string s;
	for (int i = 0; i < lineCount && fin; ++i) {
		getline(fin, s);

		iss.str(s);
		// cout << iss.str() << endl;
		iss >> cols1[i] >> cols2[i] >> cols3[i];
		// iss.str("");
		iss.clear(); // don't forget to do this!
	}

	// print(cols1, lineCount);
	// print(cols2, lineCount);
	// print(cols3, lineCount);

	// Do something ...


	// release cols
	delete[] cols1;
	delete[] cols2;
	delete[] cols3;

	fin.close();
}
