Finding minimum and mean temps from file.

[n30810c377]

I am not very good in C++, however I have this task and I really need your help here. I am using Borland C++ 4.51 compiler. I am stuck, and I dont have any lead to do this.. Here is the thing:

The following data are obtained from the file ‘klwea.txt’. It contains the twenty-four hourly average air temperatures for the months of January through December, recorded at KLIA airport.

Hi,
Declare a two dimensional array like int arr[12][12]
Read from the file element one by one and start putting the value into the array.
For every row read increment the first dimension.
After filling take one dimension and calculate the min and max and the mean(This will be an easy task).
As you are good in c++ you can easily write the code using the idea above.

Have 12 array variables each storing data for each month.
U need to read the data from the file column wise with first column going into first array variable and so on.
Once the data is fetched, finding hte min,max and the mean for each month would become easier.

I dont remember I am good in C++ .. FACT is, I am totally suck in this.. And to make it worst, I dont even understand what are u guys talking about .. :-(

Then I'd recommend starting here. Work through each of those tutorials, and then go back and read those posts, see if they make sense.

Another option (if this is a class assignment) is to research the individual terms that don't make sense to you, and build a better idea of what they are suggesting. However, if this is a class assignment, you should re-read what your instructor gave as that usually relates to the assignment.

[n30810c377]

Hi everyone..

Too bad this is not a class assignment. It is just a project that someone suggested to me just to make it 'clear' for everyone who view my major : building the airport. Anyway, let us just forget about my major and get back to this problem.

So, here is what I figure out myself. I started with this file as klwea.txt and have these in the file:

Please note that the first line is month (it has 12 months) and the first row is time (it has 24 hours). And this is my progress:

#include <iostream.h>
#include <fstream.h>
 
int main()
{
ifstream input;
int i, j;
double num[25][13];
int count=1;
 
 
input.open("klwea.txt");
 
if(!input)
cout<<"Error\n";
 
else          // This part will display the whole value of the klwea.txt
{
 
    for (j=1;j<13;j++)
    {
    input>>num[0][j];
    cout<<"num[0]["<<j<<"]="<<num[0][j]<<"    "<<endl;
    }
 
    for (i=1;i<25;i++)
    {
    for (j=0;j<13;j++)
    {
    input>>num[i][j];
    cout<<"num["<<i<<"]["<<j<<"]="<<num[i][j]<<"    "<<endl;
    }
    }
}
return 0;
}

So, whats next?? Anyone can give me any idea or help me doing this..? Thanks anyway for reading..


Million thanks to you,

Hi,
You asked for help and you are also scolding the guy who helped you.
What sort of attitude you have?
The way you have replied is very bad.

For Forum Leaders,
Some action has to be done for this.
