Hi everyone,

I have a 2d array whith 50000 lines and 14 columns, and I have to sum/multiply each value of a column for a fixes numbers, like this:

a[1][14] = 0 a[1][14] + 2 = 2

a[2][14] = 2 a[2][14] + 2 = 4

a[3][14] = 5 a[3][14] + 2 = 7

How I do this for all the numbers?

I do this:

```
float data3 = 0;
float data4 = 0;
data3 = data[1][1] + 2;
data4 = data[2][1] + 2;
cout << data3 << "" << endl;
cout << data4 << "" << endl;
```

And I like to put the values into an another 2d array with "n" lines and 1 column.

Than I have to find the maxValue of this 2d array with 1 column.

Can you help me?

Thanks
