Design and write an object-oriented program for managing inventory bins in a warehouse. To do this you will use two classes: InvBin and BinManager. The InvBin class holds information about a single bin. The BinManager class will own and manage an array of InvBin objects. Here is a skeleton of what the InvBin and BinManager class declarations should look like:

class InvBin

{

private:

string description;

int qty;

public:

InvBin (string d = "empty", int q = 0)

{

description = d;

qty = q;

}

void setDescription(string d);

string getDescription() ;

void setQty(int q);

int getQty( ) ;

};

class BinManager

{

private:

InvBin bin[30];

int numBins;

public:

BinManager()

{

numBins = 0;

}

BinManager(int size, string d[], int q[])

{

}

string getDescription(int index);

int getQuantity(int index);

string displayAllBins();

bool addParts(int binIndex, int q);

bool removeParts(int binIndex, int q);

};

#include <cstdlib>

#include <iostream>

using namespace std;

int main(int argc, char *argv[])

{

class InvBin {

private:

string description;

int qty;

public:

InvBin(){ description = ""; qty = 0;}

InvBin (string d, int q) { description = d; qty = q;}

void setDescription (string d){description = d;}

void setQty(int q){qty = q;}

string getDescription() {return description;}

int getQty(){ return qty; }

};

class BinManager {

private:

InvBin bin[30];

int numBins;

public:

BinManager() {numBins=0;}

BinManager(int size, string d[], int q[])

{

int i;

for(i=0; i<size; ++i)

{

bin[i].setDescription(d[i]);

bin[i].setQty(q[i]);

}

numBins = size;

}

void setDescription (int b, string d) {bin[b].setDescription(d); }

void setQty(int b, int q) { bin[b].setQty(q); }

string getDescription(int b) { return bin[b].getDescription();}

int getQty(int b) { return bin[b].getQty();}

bool addParts(int b, int q)

{

int temp;

if(q < 1)

return false;

else

{

temp = bin[b].getQty() + q;

bin[b].setQty(temp);

return true;

}

}

bool removeParts(int b, int q)

{

int temp;

if (q < 1 || bin[b].getQty() < q)

return false;

else

{

temp = bin[b].getQty() - q;

bin[b].setQty(temp);

return true;

}

string displayAllBins()

{

int i;

for(i=0;i<numBins;++i)

cout << i+1 << ". " << left<< setw(20) << bin[i].getDescription()

<< right << setw(4) << bin[i].getQty() << endl;

}

};

system("PAUSE");

return EXIT_SUCCESS;

}
