Binus’s Used Cars, Inc. employs several salespeople. Mr. Robert, the owner of the company, has provided a file that contains sales records for each salesperson for the past month. Each record in the file contains the following two fields:
The salesperson’s ID number, as an integer
The amount of a sale, as a real number
The records are already sorted by salesperson ID. Brewster wants you to design a program that prints a sales report. The report should show each salesperson’s sales and the total sales for that salesperson. The report should also show the total sales for all salespeople for the month. Here is an example of how the sales report should appear:
The struct song is defined as :
typedef struct {
char* title;
char* artist;
int year;
} song;
Write the following two functions maintaining a database of entries of type song in a file in c language .
(int add_song(const char* file_name, const song s);The function gets the name of a file, and a song. If the song is not in the file, the function adds
it to the file and returns 1. Otherwise, the function does not modify the file and returns 0.
song* find_song(const char* file_name, const char* title);
The function gets the name of a file and a title of a song. It searches the file for the song with the given title. If a song is found, it returns a pointer to the song with all the details. If not found, the function returns NULL. You may assume the song titles are unique.

- 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.

- COBOL PROGRAMMING you will need to create your own Input file records. You must have at least 10 records in your file. You can make up your own Customer Last Name, First Initial, Car types must be one of the following TOYOTA, OLDSMOBILE, CADILLAC. You can also make up your own Miles and Days rented. Make sure to use the data lengths used in the Customer Record layout. Don't forget to format your output. Hint: You will be using several IF statements for this program. Since the Car-Type is an alphanumeric when you compare your type use quotes. For example .. IF CUST-TYPE-IN = "1" ...... keep in mind you can use double or single quotes. Also, don't forget that the first 100 miles are free regardless of car type.

The data should be private, and should include a firstname, lastname, array of three grades, and a field for average grade. Build two constructors: a default constructor and a constructor that takes the first and last name. Build a function to read the data, either from a file or from cin. The read function reads the two names and three grades, but does not read the average grade. Build a write function that writes the data either to a file or to cout. The write function prints all of the data on one line with spaces between fields. Build a function to calculate the average grade field. Build an overloaded operator == to compare two records. This should be implemented as a friend function. Declare the constructors and functions in the body of the class, but implement them outside the class.

Here is the definition of the struct song: typedef struct { char* title; char* artist; int year; } song; int add_song(const char* file_name, const song s); 1. The function gets the name of a file, and a song. If the song is not in the file, the function adds it to the file and returns 1. Otherwise, the function does not modify the file and returns 0. song* find_song(const char* file_name, const char* title); 2. The function gets the name of a file and a title of a song. It searches the file for the song with the given title. If a song is found, it returns a pointer to the song with all the details. If not found, the function returns NULL.
