Read Multidimesional Array from Data Files

[farizaz]

Hi!

I'm new here also just learned the program. I'm trying to read 2-dimensional data from data files. It seems to display weird numbers. I think I don't know how to read the data files. Hopefully i can learn from someone.

Post the code that's not working. Someone will tell you what's wrong with it.

The code is given below:


int main()
{
// ifstream constructor opens the file
ifstream inClientFile( "example.tx t", ios::in);

// exit program if ifstream could not open file
if ( !inClientFile)
{
cerr << "File could not be opened" << endl;
exit(1);
} // end if

double itemsets[6][5];
int row = 6;
int column = 5;

cout << left << setw(5) << "Itemsets" << endl;

// display each record in file

// while(inClientF ile >> itemsets[row][column])
for (int i=0; i<row; i++)
{
cout << itemsets[i][0];
for (int j=0; j<column; j++)
{
inClientFile >> itemsets[row][column];
}
}
outputLine(item sets);

return 0;
} // end main

// display single record from file
void outputLine( double itemsets[6][5])
{
int row = 6;
int column = 5;

for (int i=0; i<row; i++)
{
cout << i;
cout << itemsets[i][0];
for (int j=0; j<column; j++)
{
cout << j;
// cout << left << setw(10) << itemsets[][j];
if ((j+1)%5 == 0)
cout << endl;
}
}
} // end function outputLine

If i and j are counters why do you put row and columns as the matrix indexes?

[CODE=cpp]inClientFile >> itemsets[row][column];[/CODE]

Thank you very much!
