how do i count lines?

[mymyzzz]

i need to know how many times the while loop is done.

while (myin)
    {   
        myin >> name;
        cout << name ;
        myin >> num1 >> num2 >> num3;
        cout << "     " << fixed << setprecision(0)<< num1  << "  "<< num2 << "   "<< num3 ;
        average = (num1 + num2 + num3)/3;

        cout << " " << fixed << setprecision(2)<< average ;
        if ( average >= 90)
            cout << "     A";
        else if( average > 80)
            cout << "     B";
        else if( average > 70)
            cout << "     C";
        else if( average > 60)
            cout << "     D";
        else
            cout << "     F";

        cout << endl;
    }

i have multiple name and numbers so this repeats.

i want to know why last one is repeated?

also, i need to get an average of all of the averages, how can i do it?

int counter=0;

while(...)
{
     ...
     ...
     ...
    counter++
}

cout << "The while() loop executed " << counter << " times.";

int counter=0;

while(...)
{
     ...
     ...
     ...
    counter++
}

cout << "The while() loop executed " << counter << " times.";

YOu are awsome Thanks!!!

but why does my program repeat the last string?

I have a feeling you may have place program output inside of a loop.

Let us see ye' code.

counter = -1;   
while (myin)
{
    while (myin)
    {   
        myin >> name;
        cout << name ;
        myin >> num1 >> num2 >> num3;
        cout << "     " << fixed << setprecision(0)<< num1  << "  "<< num2 << "   "<< num3 ;
        average = (num1 + num2 + num3)/3;

        cout << " " << fixed << setprecision(2)<< average ;
        if ( average >= 90)
            cout << "     A";
        else if( average > 80)
            cout << "     B";
        else if( average > 70)
            cout << "     C";
        else if( average > 60)
            cout << "     D";
        else
            cout << "     F";

        cout << endl;
        counter++;
    }

}
cout << "The class average is " << endl;
cout << "There are " << counter <<" students\n";

its a program to calculate the average and grade it.

also, how do i get the average of average?

i am running low on time because i need to turn this in by 12:00.
thanks for all your help!!!

how do i get the average of average?

add up all the tests and divide by the total number of tests.
