- A user wants to write a C program for manipulating student records. The program contains a function for accessing the student file. The user wants to add some records to the file. Which of the following line of code is used to open the student file for implementing this functionality? Choose an answer A fp = fopen ("studentfile.dat", "r"); B ch = fgetc(fp); C fp = fopen ("studentfile.dat", "w"); D fputc (ch, fp);In C language, write the following two functions maintaining a database of entries of type song in a file. 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. You may assume the song titles are unique. Additional instructions and hints: 1.

- In C program Create Student Library with the following components: student_t : user-defined type (StudentID, FirstName, LastName, GPA). scan_student() : function to read (StudentID, FirstName, LastName, GPA). print_student(): function to print a student’s information as follows: Name: John SmithStudent ID: 123456 GPA: 3.5 Create student.h, student.c and main-student.c In main-student.c prompt the user to enter the information needed to create 2 student records then display them in the order they were entered.Question 1 of 1: Word Swap: Write a C++ program that will swap the words Caesar and Brutusin the file “source_file.txt”. You will need to load the file “source_file.txt” and finally write theupdated contents with the replaced words to the file “target_file.txt”.Successful operation should swap all occurrences of Caesar with Brutus and Brutus with Caesar.You can use functions from the cstring library. You are not allowed to use the string datatype.Please properly comment your code before submission.IN C++ Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Hints: Use the find() function to find the index of a comma in each…
