File Merging in C++

UNIX's repository is picky as hell jesus christ

Program is working. As far as I could tell, I did everything the assignment asked for. But using system("pause"); was a bad idea since it's not portable. I used cin.get(); instead, but now my program closes anyway. What's a working portable equivalent to system("pause")?

EDIT: Okay... it took that regardless. Whatever, I'll take it.

Also, this is one of the results on the repository...

"... check for ''inF.clear();+inF.seekg(+0L,+ios+::+beg+);'' ==> NOT FOUND"

Uh... but in my code I...

Code:

int Sum (istream & inF)
{
    inF.clear();
    inF.seekg(0L, ios::beg);  <--- IT'S RIGHT THERE.

    int sum = 0;
    int num;
    while (inF >> num)
    {
        sum += num;
    }
    return sum;
}
