C++

For this lab, please write a program that uses a structure to store the following inventory data in a file:

1. Item Description (Must be a char array)

2. Quantity on Hand (int)

3. Wholesale Cost (double)

You must use the starter program below (page 2) and you should not add anything to main.

Just write the code for:

1. addRecord

2. viewRecord

3. changeRecord

Input validation for Item Quantity and Cost: (4 X 3 = 12 points)

1. Must be numeric

2. Must not be negative

3. Must be greater than zero

There is no validation for the Item Description.

File specifications:

You must submit the test file (with reasonable inventory names) that you created while testing your program. The test file should have at least 5 entries and have an extension of .dat The file path to the test file should be C:\temp *** The file format MUST be binary***.

On Exit: (NOTE: this requirement is not represented on the sample output below)

Print to the screen: Thank you for visiting the store where is your last name.

Starter Code:

/* *** Your Name Here ***

struct Inventory

char desc[30];

// Function prototypes

void addRecord(fstream &);

void viewRecord(fstream &);

} while (choice 4);

// Process the selection.

switch (choice)

{

// Choice 1 is to add a record.

case 1:

addRecord(inventoryFile);

break;

// Choice 2 is to view a record.

case 2:

viewRecord(inventoryFile);

break;

// Choice 3 is to change a record.

case 3:

changeRecord(inventoryFile);

}

} while (choice != 4);

system ("pause");

return 0;

}

Sample Output:
