#include<iostream>
#include <string>
#include <fstream>
#include <iomanip>
using namespace std;

const int SIZE = 25;//Size of arrays

int main()
{
double SalesAmounts [SIZE]; //Sales amounts array
string SalesReps [SIZE]; //Names of sales representativesarray
ifstream infile; //Input filestream variable
string fnameopen, fnameclose; //Variables to hold actualname of file
double sum;
    int counter; //used in for loops
double average; //average of sales amount

cout<<"Pleaseenter name of input file"<<endl;
cin>>fnameopen;
infile.open(fnameopen.c_str());
cout<<"Please enter name of outputfile"<<endl;
cin>>fnameclose;

sum = 0;
for (counter=0; counter<SIZE; counter++)
    {
     cin>>SalesAmounts[counter];
      sum = sum +SalesAmounts[counter];
      average = sum/SIZE;
    }
cout<<fixed<<showpoint<<setprecision(2);
cout<<"Average slaes: "<<setw(7)<<"$"
     <<setw(7)<<average<<endl;

Explanation / Answer

please rate - thanks problems: you were reading from cin (keyboard) not file don't have 25 records(probably) but reading 25 calculating average in loop and dividing by 25 should calculate outside loop and divide by # of #'s not inputting name #include #include #include #include using namespace std; const int SIZE = 25; //Size of arrays int main() { double SalesAmounts [SIZE]; //Sales amounts array string SalesReps [SIZE]; //Names of sales representativesarray ifstream infile; //Input filestream variable string fnameopen, fnameclose; //Variables to hold actualname of file double sum;     int counter=0; //used in for loops double average; //average of sales amount cout
