You are given a dataset about some all-wheel-drive cars and how much fuel they use. This data file is a subset of a public available CSV file: https://corgis-edu.github.io/corgis/csv/cars/.” you can download the input file from here”. It allows consumers to directly compare cars.
Write a program to find the top 10 cars with highest city mpg. Write the results in the output file. The input file is a CSV file with the following fields for each car: Identification (String), Classification (String), Engine Type (String), Transmission (String), City mpg(Integer), Fuel Type (String), Highway mpg(integer). Fields are separated by comma, with each car on a separate line:
2009 Audi A4 Sedan 3.2, Automatic transmission, Audi 3.2L 6 cylinder 265hp 243ft-lbs, 6 Speed Automatic Select Shift, 17, Gasoline, 26
….
Classification: whether this is a “Manual transmission” or an “Automatic transmission”. If it is unknown, it is left blank.Identification: a unique ID for this particular car, using the year, make, model, and transmission type.
Example input/output:
Enter the file name: cars.csv
Output file name:
Top10_city_mpg.csv
Technical requirement:
1. Name your program cars_mpg.c.
2. The output files should be the named Top10_city_mpg.csv.
3. Assume that there are no more than 6000 cars in the file. Assume that each field is no more
than 150 characters.
4. Use fscanf and fprintf to read and write data. To read all fields of a car, use the following
conversion specifier for fscanf:
“%[^,], %[^,], %[^,], %[^,], %d, %[^,], %dn”
5. The program should be built around an array of car structures, with each car containing
information of engine type, transmission, city mpg, fuel type, highway mpg, classification,
and identification.
6. Your program should include a function that sorts the cars by city mpg. You can use any
sorting algorithms such as selection sort and insertion sort. Note that with different sorting
algorithms, the result might differ when city mpg are the same.
void sort_city_mpg(struct car list[], int n);
7. Output file should be in the same format as the input file, with the members separated by
comma and each car on a separate line.
2012 Subaru Impreza Hatchback 2.0i, Manual transmission, Subaru 2.0L 4 Cylinder 148 hp 145 ft-lbs, 5 Speed Manual, 25,
Gasoline, 34

Programming Style Guidelines
1. Your program should begin with a comment that briefly summarizes what it does.
2. In most cases, a function should have a brief comment above its definition describing what it
does. Other than that, comments should be written only needed in order for a reader to
understand what is happening.
3. Information to include in the comment for a function: name of the function, purpose of the
function, meaning of each parameter, description of return value (if any), description of side
effects (if any, such as modifying external variables)
4. Variable names and function names should be sufficiently descriptive that a knowledgeable
the reader can easily understand what the variable means and what the function does. If this is not
possible, comments should be added to make the meaning clear.
5. Use consistent indentation to emphasize block structure.
6. Full line comments inside function bodies should conform to the indentation of the code where
they appear.
7. Macro definitions (#define) should be used for defining symbolic names for numeric constants.
For example: #define PI 3.141592
8. Use names of moderate length for variables. Most names should be between 2 and 12 letters
long.
9. Use underscores to make compound names easier to read: tot_vol or total_volumn is
clearer than totalvolumn.
