Writing to a file

[pushpa416]

Hi,

I am reading a txt file and comparing the values, and I want to substract max and min values and output all the values in a txt file or display on the screen when I push the button. please find the code below for comaprision

@
for (row = 0; row < 550; row++){
QByteArray line = file.readLine();
QList<QByteArray> numbers = line.split(',');
for (column = 0; column < numbers.size(); column++) {
data = numbers[column].toInt();
if (data > max[column])
max[column] = data;

            if (data < min[column])
                min[column] = data;
        }

result = (max[column] - min[column]);
}
@

and the ouput is like output of the result[row][column]
@
row =1
column=200000
@

It works perfectly fine for comparision and subtraction, I can output each column output separately but I want to output array[columns], subtracted values at once, I stuck there

any suggestions would be appreciated

thanks

Hi,

I don't understand what do you want do.

at line 12 'result' is computed once per row with column equals to numbers.size() +1
