Note : you have to use file handling
Question :
you are asked to make a program in c ++ in which you have to Write a function to search for student details ( name and class ) from a file using the enrollment of student.
Step by step
Solved in 2 steps
- (Data processing) Write a C++ program that reads the file created in Exercise 4 one record at a time, asks for the number of hours each employee worked each month, and calculates and displays each employee’s total pay for the month.(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.(Data processing) Write a C++ program that allows the user to enter the following information from the keyboard for each student in a class (up to 20 students): Name Exam 1 Grade Exam 2 Grade Homework Grade Final Exam Grade For each student, your program should first calculate a final grade, using this formula: FinalGrade=0.20Exam1+0.20Exam2+0.35Homework+0.25FinalExam Then assign a letter grade on the basis of 90100=A,8089=B,7079=C,6069=D, and less than 60=F . All the information, including the final grade and the letter grade, should then be displayed and written to a file.
- (Data processing) a. Write a C++ program that opens a file and displays its contents with line numbers. That is, the program should print the number 1 before displaying the first line, print the number 2 before displaying the second line, and so on for each line in the file. b. Modify the program written in Exercise 6a to list the file’s contents on the printer assigned to your computer.In C programming, write a program that creates a file in C and appends the following details from the user: Student Number: Name: Course: Age: Note: Use struct to store the input values from the user and same struct be used to append its values to the created file.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.

For the instructions on how to read and write to files see section "C Programming Files" in https://www.programiz.com/c-programming or…In C++ Create a function that checks to see if a file existsIn C Programming Language. - use user-defined functions.- use an array of arrays.- use file pointers- use string processing and character conversions.- use a dynamic memory function calloc() or malloc() - Demonstrate the ability to read a file and process the data. Problem: You are tasked to write a program that will perform a statistical analysis of student records. Your program will open a text file (provided) and store the values read into an array (2d). Your program will then close the input file and process the data. Your program will print out the records to screen and will then print out the average quiz scores per student.For each student in the provided text input file there is a name of up to 20 characters, an id number of five alphanumeric values (n1234), 4 exm grades in order: exm 1 – exm 4.You may use a fixed 2d array size of 80 characters for the input file name. You must use a dynamic array for at least one task in your program. You may declare your filename array using…
- 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.

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.Instructions Write a C/C++ program that calculates the least squares line for two sets of values. The program consists of several functions which are described below. int ReadFile (int *, int *); Write a function that reads the contents of a text file (Data1.txt) into two separate integer arrays. The function receives two integer pointers to arrays as parameters. The contents of the text file that is attached is structured as follows: Each line in the file contains two values that are separated by a comma. The values on the left of the comma, are stored in one array and the values on the right side is stored in the other array. The number of lines that are read from the file and stored in the arrays are returned to the calling statement. Tip: a single fscanf can read into multiple variables. Ex. the statement fscanf(fp, "%s %s\n", name,surname) will read the line John Doe and save the name and surname separately. (Note the space between %s and %s indicates that there is a space in the…Merge two files (1 point) Write a program that reads the content of two files “text1.txt” and “text2.txt" line by line and merges them into another file called “merge12.txt". You can safely assume that the input is valid. IN C PROGRAMMING
