why am i getting so many numbers from my array c++

Question

I'm still working on this project and I have most of my problems fixed. The problem shows itself while using selection B, but lies in option A and sending the array to the .txt file. There are a lot of extra numbers being added to the .txt file. When I cout, it displays the numbers in the array like it should, but in the text file it looks like this Anthony201910181114-8589934604445358131768008182078541176802418196927161130726102120444535893 everything before the - is correct, but all of these numbers after need to go. Why is this happening and how can I fix this? Thank you.

int main()
{
    int Stats[6];
    char Selection;
    string Character1;
    int i;
    char keep;




    do
     {

                            while ( getline (displaycharacter,Character1) )
                            {
                                cout << Character1 << endl;

            else
                break;
    }



while ( (Selection != 'c') || (Selection == 'C') ); // ends the program is c or C is entered.
return 0;
}       

int GenerateScore()

    int roll1 = rand()%6+2;
    int roll2 = rand()%6+2;
    int roll3 = rand()%6+2;
    int sum;

       sum=roll1+roll2+roll3;


      return sum;
}

Like was mentioned in the comments:

while ( (keep='n') || ('N') );

should (at least) be changed to

while ( (keep == 'n') || (keep == 'N') );

Also, this loop:

for(int i = 0; Stats[i]; i++)

Will only terminate when Stats[i] evaluates to false, which will only happen when Stats[i] == 0. This loop is causing the extra chars in the file: the code keeps accessing out of bounds array elements until randomly the out of bounds element == 0. You probably want for(int i = 0; i < 6; i++)
