Need help and some tips on how to get this program to work. The program takes in integer numbers from a .dat file and puts them into an array. I have been able to read the number from the .dat file but i also need to be able to output 3 more values to the .dat file from user input. Once all the values are in the array, the program uses a reverse bubble sort method of sorting the values of the array. There is something going wrong with my b_sort function but im not quite sure what it is.

What I need:

Implementation of the load_from_file function

Implementation of the save_to_file function

Correction of the b_sort function

-----------------------------------------------------------------------------

Here is what I have in my main so far:

#include #include #include #include "numlist.h"

using namespace std;

int main(){ ifstream inputfile; string inputfilename; int array_size = 1000; char * array = new char[array_size]; cout << "Input file name: "; getline (cin, inputfilename); inputfile.open(inputfilename.c_str(),ios::in | ios::binary); string line; if (inputfile.is_open()){ int position = 0; int numToSave; cout << "file opened successfully "; while (!inputfile.eof() && position < array_size){ inputfile.get(array[position]); position++; }

for(int i = 0; array[i] != '\0'; i++) { cout << array[i]; } inputfile.close(); } else cout << "Unable to open file "; return 0; }

Here is the numlist.cc

---------------------------------------------------------------

#include "numlist.h" #include #include #include using namespace std;

// Constructor NumList::NumList(){ used = 0; }

void NumList::insert(int num){ if(used

void NumList::load_from_file(istream& ins){

} void NumList::save_to_file(ostream& outs){

} void NumList::see_all()const{ if(used == 0) cout<<"Empty list. "; else for(size_t i = 0; i= 0; --j){ if(data[j] < data[j-1]){ done = false; tmp = data[j]; data[j] = data[j-1]; data[j=1] = tmp; } } } }

Here is numlist.h

-----------------------------------------------------------

#ifndef NUMLIST_H #define NUMLIST_H #include #include #include

class NumList{ public: static const size_t CAPACITY = 100; // Default constructor NumList();

void insert(int num); size_t size()const {return used;}

void load_from_file(std::istream& ins);

void save_to_file(std::ostream& outs); void b_sort(); int get_item(size_t index)const; void see_all()const; private: int data[CAPACITY]; size_t used; };

#endif

And finally here is the smaller.dat file

-----------------------------------------------------------
