Write a program to read an unknown number of integer numbers stored in a file
nums.txt and calculate the number of negative, the number of
positive numbers and the
number of zeros. Your application should display on the screen the number of negative
and positive numbers as well as the number of zeros.

What have you tried so far? And please don't say "I don't know how to start", because that's an extremely lame excuse. Anyone with a passing familiarity with C++ should be able to write this as a starting point:

#include <fstream>
#include <iostream>
int main()
{
ifstream in("myfile.txt");
if (in)
{
int num;
while (in >> num)
{
cout << num << '\n';
}
}
}

In what way does ofstream represent an input file? Take a look at my basic starting point example and work from there. You're reading a file, not writing one.

Right now all it does is print out the numbers. I'm not going to write the whole thing for you, so try to finish up that last part. I assure you, it's quite simple. I'll even give you a hint: use three counter variables and increment them appropriately for each number, then print those counters after the loop ends.

Need some help with this Array. I am trying to get the sum of the even numbers and the sum of the odd numbers using a for each loop. I know the answers to what I am trying to achive are sum of even = 84 and the sum of ...

When I execute this progammatically, I get a table with row heights much larger than when I do this manually.

Note : Sel is the Word.Selection object and the Clipboard contains an Excel Table.

public void AddClipboard()
{
Sel.PasteExcelTable(false,false, false);
var t = Sel.Tables[Sel.Tables.Count];
t.AutoFitBehavior(Word.WdAutoFitBehavior.wdAutoFitContent);
}

I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).
the function that I created to find the ...
