Averaging Based on Internal Calculation
Hi, hoping someone can point me on the right road here...
I'm working on a program that reads data from a .in file. The data is for a payroll program (I know...but it's a good start for beginners!). I have everything working as far as the data being read and the functions that calculate the necessary information (netpay, tax rate, etc.). The next step is to have the program also tell me the average dollar amount of the netpays it has calculated. I understand how to sum and average if a user inputs the numbers that are to be worked with but not how to do the same calculations using data that the program has created itself. Basically, I'd like the program to output the statement "The average net pay for this period is: <AvgNetPay>" after the rest of the output. Any help would be much appreciated. My current code is as follows. I'm using Dev C++ for a compiler.

I figured it out.
Added:
float findaverage(float netpay[], int n){
for(int i=0; i<n;i++){
sum=sum + netpay[i];
c=c+1;
average = sum/c;
}//End For
}//End Findaverage
(after void findnetpay)
and added:
float sum=0;
float average=0;
float c=0;
(as global variables)
Once that was in I was able to add code to the output after the final For:
cout<<setw(8)<<"The Total Net Pay is: $"<<sum<<endl;
cout<<setw(8)<<"The Average Net Pay is: $"<<average<<endl;
Works great. Whew! I hate when I bang my head on the desk for a few hours. Now I'm off to see if I can get it to sort the netpay. Wish me luck!
