// a structure called prod

struct prod

{

string name;// – a string, assumed to have no spaces

double price; // –adollaramount

int inStock; // – the number of items currently in stock.

};

//Fucntion Prototypes

void readInventory(prod products[], int& size);

/*===============================================*/

/*returns: a dollar amount, the total value of the inventory*/

double totalValue(prod products[], int size);

/*===============================================*/

// Sorts the given array by name

void sort(prod products[], int size);

/*===============================================*/

/*a report to a file called “report.txt”.

When the file fails to open, print

“Unable to open output file.” and end.*/

void writeReport(prod products[], int size);

/*===============================================*/

//Function definitions

/*===============================================*/

cout << "Report written to file\n";

//close the output stream

outfile.close();

}

/*===============================================*/

void sort(prod products[], int size)

{

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

{

for (int j = i+1; j < size; j++)

{

if (products[i].name > products[j].name)

{

//swapping

products[j] = temp;

}

}

}

}

/*===============================================*/

double totalValue(prod products[], int size)

{

double total = 0;

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

{

total += products[i].inStock * products[i].price;

}

return total;

}

/*===============================================*/

void readInventory(prod products[], int& size)

{

// Open a file called “inventory.txt”

//and read the data from the file into the partial array

//.If the file fails to open,

//print “Unable to open input file”

//and set the number of products to 0.

size = 0;

ifstream inFile("inventory.txt");

if (!inFile)

{

return;

}

string name;

double price;

int qunatity;

while (inFile >> price >>qunatity >>name)

{

products[size].price = price;

size++;

}

}

cout << "inventory read\n";

//close the stream

inFile.close();

}

/*===============================================*/

int main()

{

//declares a partial array of products

prod products[100];

int size;

// invokes readInventory()

readInventory(products, size);

// invokes sort()

sort(products, size);

// invokes writeReport()

writeReport(products, size);

// ends with the standard system pause.

system("pause");

return 0;
