calculating a sum with two variables from user created output file - c++

Question

I'm trying to figure out how exactly I'd use my output text file I created to be used to calculate the sums of both variables. My output text file is saving the information correctly, but I get 0 and 0 for my sums so it's not reading the information I think. Also, does the information I enter into the arrays only save into the text file? I need it only being saved into the text file so that the sum calculations are only receiving information from the text file
#include <iostream>
#include <string>
#include<iomanip>
#include <fstream>
using namespace std;
int main() {
int ItemNumber[2];
float price[2];
int sumnumber = 0;
float sumprice = 0;
string myfile = "c:/Users/rz/Desktop/numbers.txt";
int count = 0;
ofstream outFile;
outFile.open(myfile);
while (count <= 1)
{
cout << "enter a price" << endl;
cin >> price[count];
outFile << price[count] << endl;
cout << "enter a item number" << endl;
cin >> ItemNumber[count];
outFile << ItemNumber[count] << endl;
count++;
}
outFile.close();
fstream inFile;
inFile.open(myfile);
while (count <= 1)
{
sumprice = sumprice + price[count];
sumnumber = sumnumber + ItemNumber[count];
}
cout << sumnumber << endl;
cout << sumprice << endl;
system("pause");
return 0;
}

Answer 1

At the end of the first loop:
int count = 0;
while (count <= 1) { ... count++ ... }
the variable count will be set to 2.
Then, when you start the second loop:
while (count <= 1) ...
the condition is already false, hence the body of the loop will never be executed.
In order for this to work, you would have to reset count back to zero so that it runs through the items again. Or, better yet, leave count alone (since it indicates how many items were processed) and use another variable to got through them:
for (int i = 0; i < count; ++i) { ... use i rather than count ... }
