 file.close();
 
    fstream output;
    output.open("Output.txt");
    output << (people-count) << endl;
    for (int j = 0; j < (people-count); j++)
    {
        
       
        if(records[j].isdeleted==true)
        output << records[j].iD << " " << records[j].firstName << " " << records[j].lastName << " " << records[j].examGrade;
        
    }
first, i wouldnt use fstream... second, records[j].isDeleted == true is redundant. why not just make it records[j].isDeleted. third, we need more code. how else can we know from so little information?
First of all, you should ALWAYS test the stream first:
1
2
3

if(!output)
{
cerr << "Could not open file to write to";
return -1;
}

or similar.

Then, I would step through your program with the debugger to see what's happening. It's possible your if statement in the for loop never evaluates to true.
