1. ## Reading a file into a two dimensional array!!

Hello guys,
I'm trying to read a minimum value from a file, but the file contain two minimum values that are the same. Here's a example

file

32 345 23 122
21 23 233 239
132 252 21 231
673 141 45 211

How could I specify that the minimum value is located at column 1 and the other is located in column 3

This is what I have so far

Code:
```
double power [NROWS] [NCOLS], min;
string Days[7] = { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};
int weeks [10] = { 1,2,3,4,5,6,7,8,9,10};
int set_day, set_week;
cout << "--[ Minimum Daily Power Output] --" << endl;
ifstream inFile;
inFile.open("power1.dat");

if (inFile.fail())
{
cout << "Error opening The file " << endl;
}
else
{
for ( int i = 0 ; i <= NROWS -1; i++)
{
for ( int j = 0; j <= NCOLS-1; j++)
{
inFile >> power [i] [j];
}
}
}
for (int i=0; i<=NROWS -1; i++)
{
for ( int j = 0; j <=NCOLS -1 ; j++)
{
if	( i == 0 && j == 0)
min = power[i][j];
else
{
if ( power[i][j] <= min )
{
min = power[i][j];
set_day = j;
set_week = i;
}
}
}
}

cout << "\n\n Minimum Output is = " << min <<" megawatts" << endl;
cout << " Occurred on = " << Days[set_day] << " of week "<< weeks[set_week]<< endl;
system("pause");```

2. Hi!!!!

Your request looked so urgent, I wanted to let you know I am reading your post!!!! I haven't had time to finish your post!!! But when I do, I'll see if I have a solution!!! Oh, heck!! I give up!! I just don't think there's enough time!!!

3. thats fine just give me a solution when you get some time thanks

4. You'll need to find a way to store multiple values, maybe using std::vector. push_back() each new minimum position into the vector. If a new minimum element is found, clear() the vector. When doen, return the entire vector and print it's contents individually.

5. that sounds as a good Idea but I don't know how to use vectors, however is there another easier way to do that ?
Thank you

6. Yes, dynamically allocate memory from the heap manually and reinvent the wheel. And spend nights up fixing segfaults.

Or learn how to use vectors.

Thank you
Using vectors is the easier way... Take the time to learn how to use STL containers before looking for the alternative.
