2D Arrays

[mrnguuyen]

Hello. I am having troubles input filing. Any help would be greatly appreciated. :)

This is what the input file looks like:

12
Ami
Ann
Ben
Dan
Ema
Ira
Guy
Leo
Luc
Meg
Sue
Tom
0 0 0 0 0 0 0 1 0 0 1 0
0 0 0 0 0 0 0 0 1 1 0 0
0 0 0 1 0 0 0 0 1 0 0 0
0 0 1 0 0 0 0 0 1 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 1 0 0 0 0 0
0 0 0 0 0 1 0 0 0 0 0 0
1 0 0 0 0 0 0 0 0 0 0 0
0 1 1 1 0 0 0 0 0 1 0 0
0 1 0 0 0 0 0 0 1 0 0 0
1 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0

These are my errors I get in my program:

"readData(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >*, int (*) [12], int&)", referenced from:


_main in main.o

const int MAX_STUDENTS = 80; //Max Number of students
const int col = 12; //Number of students


void readData(string studentName[], int friendList[][col], int &studentSize); //Read data from inputfile

{
    int studentSize; //Use this to read first number of inputfile
    string studentName[MAX_STUDENTS]; //String array for student's name
    int friendList[MAX_STUDENTS][col]; //2D array for the set of numbers
    
    readData(studentName, friendList, studentSize);
    
    cout << studentSize; //Test to see if input file is correct
    
    
    
    
    return 0;
    
}

{
    ifstream inputFile;
    
    inputFile.open("3club.txt");
    if(inputFile.fail())
    {
        cout<< "Input file was unable to open." <<endl;
    }
    
    inputFile >> studentSize;
    
    for(int current = 0; current < studentSize; current++)
    {
        inputFile >> studentName[current];
    }
    
    for(int row = 0; row < studentSize; row++)
    {
        for(int col = 0; col < studentSize; col++)
        {
            inputFile >> friendList[row][col];
        }
    } //End for-loop
}

I dont know what this program does. I do know you passed the wrong type of parameter in function readData, studentName array is type string

I just need help trying to read the data from the specific text file that is listed above the code. The input file "3club.txt" is the input file above the code. I am suppose to read the the studentSize which would be 12 in the first line of the text file. The names are listed into studentName[] and the matrix is stored inside of friendList[].
