When I put in the following code in Code Blocks, a file called salesSorted.txt is being created; however, it always writes 0 - it never writes the sorted data from the sales.txt file. What am I doing wrong?

#include #include #include

using namespace std;

//Function that reads data from user void getSalesData(double *sales, int n, fstream& fin) { string val;

//Iterating over file data for(int i=0; i

//Converting to double (sales data) sales[i] = stod(val); } }

//Function that sorts data using Selection sort algorithm void sortData(double *sales, int n) { double temp; int minLoc, i, j;

//Iterating over array for(i=0; i

//Looping over array to find minimum element for(j=i+1; j

//Swapping elements temp = sales[i]; sales[i] = sales[minLoc]; sales[minLoc] = temp; } }

//Function that writes data to file void writeToFile(double *sales, int n) { int i;

//Opening file in output mode fstream fout("salesSorted.txt", ios::out);

//Writing number of records fout << n << " ";

//Writing data to file for(i=0; i

//Closing file fout.close(); }

//Main function int main() { int n; string val; double *sales;

//Opening file in read mode fstream fin("sales.txt", ios::in);

//Checking file opening status if(fin.fail()) { cout << " Error!!! Opening file... "; return 0; }

//Reading number of elements fin >> n;

//Allocating memory sales = new double[n];

//Reading data from file getSalesData(sales, n, fin);

//Closing file fin.close();

//Sorting data sortData(sales, n);

//Writing to file writeToFile(sales, n);

cout << " Data has been processed and written to file... ";

//De-allocating memory delete sales;

cout << " "; return 0; }
