How do you read information from a file and send it to a array?

[canucksfan1]

Okay, I am lost on how to send information from a file that has names and numbers into the arrays so then I can display the information afterwards from the arrays.

My code so far is: I just need help with sending info and I can do the rest.

  #include <iostream> //for cin and cout
#include <fstream> //for input/output files
#include <conio.h> //for getch
#include <string> //for string

using namespace std;

void getNames(ifstream& inStream, string names[], int marks[], int numElts);
int linearSearch(const string names[], int numElts,string who);
int binarySearch(const string names[], int numElts,string who);
void selectionSort(string names[], int marks[],int numElts);
void displayData(const string names[], const int marks[], int numElts);

int main()
{
	//Variables,Constants, and Arrays
	const int NUM_NAMES = 20; //array size
	string names[NUM_NAMES];
	int marks[NUM_NAMES];
	ifstream inStream;
	int index; //index number
	string searchWho; //name of person being searched

	_getch();

}
void getNames(ifstream& inStream, string names[], int marks[], int numElts)
{
	inStream.open("database.txt");
	while (!inStream.eof)
	{
		getline (inStream,names) //Im not sure if this is what you do because I keep getting errors.

	}
}

Thanks in advance!

It depends on how it's stored.
Generally, if you're the one defining the rules, I'd go with fstream, and use >> and << operators for both saving and loading.
This way, it's easy to get data.
Look at my example:

//Loading file - LevelLoader.cpp
/**
   * A function loading level from a file
   * @param con A vector for storing Blocks from file
   * @param filepath The path of file containing data
   * @return Function returns false if couldn't open file, otherwise returns true
*/
bool LevelLoader::LoadLevel(std::vector<Block>& con, std::string filepath)
{
    std::ifstream file(filepath); // Create a file stream, open file
    if(!file.good()) // If we encounter error, return false
    {
        return false;
    }
    if(file.is_open() )
    {
        while(file.good() )
        {
            //Each file line looks like this(example): 
            // 25 64 3
            int xpos;
            int ypos;
            int colorIndex;
            file >> xpos;
            file >> ypos;
            file >> colorIndex;
            con.push_back(Block(xpos, ypos, colorIndex));
        }
        con.pop_back();//Including one empty line.
    }
    else
    { 
          return false;
    }
    return true;
}

I had to make small hack with pop_back(), but it's because that how I stored it.
As you see, I can extract needed data from file.

And function that saves it is just as similar

void CreatorState::Save()
{
    for(auto& it : m_BlockContainer)
    {
        levelFile << it.GetX() <<' '<< it.GetY()<<' '<<it.GetHp()<<std::endl;
    }
    levelFile.flush();
}

Which you could read like "For each element in m_BlockContainer, take its X, Y and HP, and store them in the file.

I'm pretty sure that if you experiment you'll do it without problem.
Cheers!

PS. If you don't want to use >> operator, then your code has a following flaw - you get line from file, but you never parse input string - you need to go through string and separate each element, take it out from string and store in proper array.
