Hello Everyone,

Off the bat I want to say that I am just learning programming so if my code is missing basics I apologize. I was hoping that you might be able to give me an example of how you would solve this problem. I've spent the better part of a week now wracking my brain over this.

I have to answer this problem:
Assume that you have the following definition of a struct:

``````struct partsType
{
String partName;
Int partNum;
double price;
int quantitiesInStock;
};
``````

Declare an array, inventory, of 100 components of type partsType.

Now take above struct definition above and:
1.Write a C++ code to initialize each component of inventory as follows: part name to null string, partNum to -1, price to 0.0 and quantities in quantitiesInStock to 0. .
2.Write a C++ code that uses a loop to output the data stored in inventory. Assume that the variable length indicates the number of elements in inventory.

I have developed to this point:

``````#include <iostream>  //Declares IO Stream
using namespace std; //Declares Namespace

for (int i = 0; i < 100; i++) //Declares Counter

{

inventory[i].partName = ""; //Sets partName = to part

inventory[i].partNum = -1; //Sets partNum counter = -1

inventory[i].price = 0.0; //Sets price = 0.0

inventory[i].quantitiesInStock = 0; //Sets counter for quantity to zero.

}
for (int i = 0; i < length; i++)

{

cout << inventory[i].partName << endl; //Output for Part Number

cout << inventory[i].partNum << endl; //Output for Part Number

cout << inventory[i].price << endl; //Output for Price

cout << inventory[i].quantitiesInStock << endl; //Output for quantities

}
system "pause";
return 0;
``````

You don't seem to have a main function.

You are trying to use the array inventory without having actually created it.

`system("pause")` is hideous and expensive and dangerous and non-portable. http://www.gidnetwork.com/b-61.html

Is this a little better in the right direction?

``````#include <iostream>  //Declares IO Stream
using namespace std; //Declares Namespace
int main ()
{

int partName;
int partNum;
int price;
int quantitiesInStock;
int inventory;

int arr[100];
for (int i = 0; i < 100; i++) //Declares Counter

{

inventory[i].partName = ""; //Sets partName = to part

inventory[i].partNum = -1; //Sets partNum counter = -1

inventory[i].price = 0.0; //Sets price = 0.0

inventory[i].quantitiesInStock = 0; //Sets counter for quantity to zero.

}
for (int i = 0; i < length; i++)

{

cout << inventory[i].partName << endl; //Output for Part Number

cout << inventory[i].partNum << endl; //Output for Part Number

cout << inventory[i].price << endl; //Output for Price

cout << inventory[i].quantitiesInStock << endl; //Output for quantities

}

return 0;
}
