C++: Matching Program

 

Create a datafile that contains the first name, last name, gender, age, height, smoking preference, eye color and phone number. Add a variety of records to the file. A sample file looks like:

Write a program that opens the file and reads the records one by one. The program will skip any records where the gender preference is not a match. Of those records that match the gender preference, check to see if the age and height are between the maximum and minum preferences. Then check to see if the smoking preference and eye color are also a match. If at least 3 of the remaining fields match, consider the record a partial match, and print it in the report. If all 4 of the remaining fields match, the record is a perfect match and print it in the report with an asterisk next to it. At the end of the program, close the file and report how many total records there were of the specified gender, how many were a partial match, and how many were a perfect match. See the sample output below.

**Sample Output**

1. **User Input:**
   - What is the gender of your ideal match (M, F, N)? M
   - What is the minimum age? 0
   - What is the maximum age? 100
   - What is the minimum height (in inches)? 0
   - What is the maximum height (in inches)? 100
   - Smoker (Y/N)? N
   - What is the eyecolor (Blue, Green, Grey, Brown)? Brown
   
2. **Output Table:**
   - **Columns:** Name, Age, Height, Smoker, Eye Color, Phone
   - **Rows:**
     - Bobby Singer | 70 | 69 | Y | Brown | 555-867-5309
     - *Dean Winchester | 43 | 72 | N | Brown | 555-867-5309
     - *Sam Winchester | 39 | 75 | N | Brown | 555-867-5309

3. **Results:**
   - There were 2 perfect matches and 1 partial match out of 4 records.

4. **Conclusion:**
   - Program ended with exit code: 0

---

**A run of the program.**

1. **User Input:**
   - What is the gender of your ideal match (M, F, N)? F
   - What is the minimum age? 20
   - What is the maximum age? 65
   - What is the minimum height (in inches)? 60
   - What is the maximum height (in inches)? 70
   - Smoker (Y/N)? Y
   - What is the eyecolor (Blue, Green, Grey, Brown)? Blue

2. **Output Table:**
   - **Columns:** Name, Age, Height, Smoker, Eye Color, Phone
   - **Rows:**
     - *Bela Talbot | 39 | 69 | Y | Blue | 555-867-5309

3. **Results:**
   - There were 1 perfect match and 0 partial matches out of 3 records.

# Matching Program in C++

Create a data file that contains the first name, last name, gender, age, height, smoking preference, eye color, and phone number. Add a variety of records to the file. A sample file looks like:

```
 matches.txt 
-----------------------------------
| Charlie Bradbury | F | 42 | 65 | N | Green | 555-867-5309 |
| Bobby Singer     | M | 38 | 69 | Y | Brown | 555-867-5309 |
| Dean Winchester  | M | 43 | 72 | N | Brown | 555-867-5309 |
| Sam Winchester   | M | 39 | 76 | N | Brown | 555-867-5309 |
| Jody Mills       | F | 37 | 69 | N | Brown | 555-867-5309 |
| Bela Talbot      | F | 31 | 69 | Y | Brown | 555-867-5309 |
| James Novak      | M | 46 | 71 | Y | Blue  | 555-867-5309 |
-----------------------------------
```

Write a program that opens the file and reads the records one by one. The program will skip any records where the gender preference is not a match. Of those records that match the gender preference, check to see if the age and height are between the maximum and minimum preferences. Then check to see if the smoking preference and eye color are also a match. If at least 3 of the remaining fields match, consider the record a partial match, and print it in the report. If all 4 of the remaining fields match, the record is a perfect match and print it in the report with an asterisk next to it. At the end of the program, close the file and report how many total records there were of the specified gender, how many were a partial match, and how many were a perfect match. See the sample output below.
