Header files

A file with an extension that has some predefined declarations and definitions is called a header file. Every computer program imports a set of header files to perform common tasks such as getting input, displaying output, and so forth. Every language has different header files (such as C, JAVA, Python, and C++). In this article, header files are explained mainly in the context of the C/C++ language.

Question

Please write in C++. Please look at the example and the example output.

**Introduction**

In this lab, you will practice using basic input/output, structs, and arrays of structs. Be sure to read this lab thoroughly, especially the Hand-in Procedure.

**Lab**

To start your lab, you will need a struct to read data into. The struct definition should be placed above `main()` and below `using namespace std`. The struct should be called `PurchaseType` and contain the following fields:
1. `string customerID`
2. `string productName`
3. `double price`
4. `int qtyPurchased`
5. `double taxRate`

Write a complete program that:

1. Uses a user-defined function:
```cpp
void openFile(ifstream& iFile, string prompt)
```
Which gets the name of a file from the user and opens it into `iFile` by:
a. Prompting the user for a filename using `prompt` and reading the filename into a string.
b. Opening the file name obtained in (1a) into `iFile`, and verifying that it opened. If the file does not open, the program should output an error message and continue from (1a) until a valid file name is entered. See the example output for error formatting.
i. The file contains strings, integers, and doubles with 5 values per line with 10 lines of data in the file.
ii. Each line of data represents a different item purchased by a customer.

2. Creates an array of instances of the `PurchaseType` struct to hold the data from the file obtained in (1).

3. Uses a user-defined function:
```cpp
void readFile(ifstream& iFile, PurchaseType purchases[])
```
Which reads the data from `iFile` into `purchases` by:
a. `iFile` contains rows of data which correspond to the elements of the `PurchaseType` struct. Iterate through `iFile` inserting the rows of data, using `str.find()` `str.substr()`, into `purchases` until eof is hit.

4. Uses a user-defined function:
```cpp
void printPurchaseData(PurchaseType purchases[], int size)
```
Which prints the data contained in `purchases` by:
a. Using `iomanip` to nicely output all the data in a tabular format. You will need to calculate the total price for each product purchased by

## Example 3

### Command Line Execution

- **Command**: `g++ -Wall -pedantic -Werror main.cpp`
- **Execution**: `./a.out`

### File Input Attempts

1. **File Name Entered**: *wrong*
- **Error**: Invalid File

2. **File Name Entered**: *incorrect.csv*
- **Error**: Invalid File

3. **File Name Entered**: *invalid.txt*
- **Error**: Invalid File

4. **File Name Entered**: *err*
- **Error**: Invalid File

5. **File Name Entered**: *purchases1.csv*

The program will get the names from a file using getline since the file name includes spaces. The names should be read in until there is no more data to read. The program should prompt the user for the file name and read the data from the file. Note that these names might include spaces; handle your input accordingly.
