Question
Unless specifically instructed, do not prompt the user for input during the execution of your program. Do not pause at the end of the execution waiting for the user's input.
The first one is the required template that is said in the description
Please use the template Thank you!
Transcribed Image Text:The program has defined a structure named Sale.
The structure has the following fields:
string itemName
Milk
1
int quantity
5.85
double unitPrice
Whole Wheat Bread
The main function calls loadUserlnput which returns a pointer to the first Sale element in the dynamically allocated
3.75
array of Sale elements and an integer for the number of Sale elements in the array.
Napkin
3
The main function then calls printData to show the sale items including the total of each sale item and the total of the
2.35
entire list.
Раper Towel
Function printData
3
2.95
This is the function you need to complete as well as two other helper functions.
Soap
In the function body, print the report heading.
1
1.95
Then iterate through the array received through the parameters and print the data according to the required format. For
the total of each item, call getltemTotal.
The output should look exactly as follows:
At the end of the report, print the total of the entire sale items by calling getTotal.
