ou create the First object which uses the default constructor. The default constructor initializes all data to $0.$ You can use the following code to do this.

Inventory part$1$; $//$ This uses default constructor

Second object is created and initialized with the programmer hard coded data as follows:

int i $=1234$;

int q $=10$;

double p $=2\mathrm{.}5$;

Inventory part$2($i$,$ q$,$ p$)$;

To create the third object, you need to collect the data from the user. Once you collect the data from the user, insert this data into the object.
