For reading and for processing data of employee records stored in a file named employee.txt,the contents of it need to be reversed from end to beginning. Write a C program to read a file in serial way, and reverse the contents of the employee record and then, again traverse and read the record in the newly reversed file.

Make a C program that gets a source file name from a user. If the file does not exist, it will generate a proper error and exits. If the file exists, it also gets the name of two more files from the user, say destination1 and destination2. These files don't need to exist as they are files that need to be written to. If the files cannot be opened for writing, a proper error will be generated. The program then reads the source file line by line. It will copy every line that has a digit in it to destination 2 and lines that have no digit in them to destination 1. Feel free to use ctype's isdigit() function to identify digit characters. Example: If source file is: Hi My name is Veria Hello My name is John. How can I help you? I have a problem with my giga bit internet. The speed should be around 1000 but it's just 200 Sure! I can help with that. Can I have your number in case we get disconnected? Sure! My number's 647-123-1234 First file (destination 1) should be Hi My name is…
use c code to Write a C program that gets a source file name from a user. If the file does not exist, it will generate a proper error and exits.If the file exists, it also gets the name of two files from the user, say destination1 and destination2. These files don’t need to exist as they are files that need to be written to. The program then reads the source file line by line. If the line starts with an uppercase and ends with a lower case, it copies that line to dest1 (first destination file) If the line starts with a lowercase and ends with a dot (‘.’), it copies that line to dest2 (second destination file) If neither of the above hold, the program discards that line (doesn’t copy it anywhere) The program then displays a report mentioning how many lines were copied into each destination file. Don’t forget to close all the files. Example: Assume that the source file is (<NL> = new line, <EOF> end of file): Souce: “myfile.txt” This is my first…

In Python: Build a function that takes a record from your FASTA file as an argument, and returns a count of each amino acid coded for by the codons of the sequence. Keep in mind that because these records are not necessarily in the proper reading frame, so the user should be prompted to select a reading frame (0, +1, +2). You should put some thought into the presentation of your results by your main function, making sure they are clear and readable. The fasta file contains the below: >MD10G1276500 pacid=40089867 polypeptide=MD10G1276500 locus=MD10G1276500 ID=MD10G1276500.v1.1.491…
Write a program in C/C++ which is passed as command line argument a file name. Your program will read data from the file using read system call. The program will then pass the contents of the file to a pipe and create a child process. The child process will read the file’s content from the pipe.The child process does two things to the file data: 1) it removes all integers from the pipe. 2) It changes the case of all alphabets. The child process then writes the modified file data to the second pipe. The parent then reads this data from the second pipe andwrites the data(using write system call)to a new filewhose name is also passed as command line argument.The input file from which the data will be read has no size restriction. Sample file could have data like: M7 9am3 1k H23is e750n

Write a C program that, 1. writes an n x n matrix into a file named "matrix.txt" the matrix has to contain the number as it is given in the example, and n has to be given by the user 2. contains a function with the name "averageM", which o input parameters are the main diagonal (in the example: [0,1,3]) o of the matrix and the size of the main diagonal (in the example: 3) o and returns with the average of the numbers in the main diagonal (in the example: 1.33) 1. calls the "averageM" function on the matrix.txt" and displays the result on the screen Instruction for the user: "n=": Example: Input: 3 Output in the file: 001 112 223 Output on the screen: 1.33
1. Write a C++ program that reads a student grade from the screen/keyboard. The program should then use the input grade as a search key to look for the list of students with matching grade in a text file (file.txt). Each record of the student data in the text file consists of matric number and grade. Print the list of matric numbers for students whose grades match the search key value and the number of students with grades A, B, C, D and F on the screen. Do not use array in the program. An example of the text file (file.txt) is as follows. 66756 A 78954 B 64528 A 88756 C 59576 F 87412 A 76532 B 63849 A 79475 C 73645 B 67355 A If the input grade (i.e. the search key) is A, the input/output screen produced should be displayed as follows. Underlined and bold item is user input. Enter grade (search key): A 56700 D 93769 A The matric number of students with grade A: 66756 64528 87412 63849 93769 67355 Number of students with grade A: 6 Number of students with grade B: 3 Number of students…
create a program in C++ that does the extraction and analysis described above except that the tasks shall be made somewhat simpler. The program shall read from a file "inputdata.txt" containing a name and exactly five values of floating point numbers per line in the file. The first line of the file shall contain the name of the person (first and last) that gathered the data i.e. Joe Jones. The second line of the file shall be the first row of data. Your program will process all the lines in the file as described below. As the program reads each row of data, it shall do two things: it shall keep a running sum of the values read for that row, and shall also write the average of that row to a file "averages.txt". The program will continue reading from the file until it reaches the end of the file. This will entail using a "while" loop and the eof() function that is talked about in Chapter 13 of the text book. The person's name is to be read in at one time using "getline" and stored under…
Write a complete C or C++ program to implement a digital music archive program. The program should be able to allow the following operations through the menu structure. Use FILE to write the outputs, the song directory: Menu: 1- Add a new song to directory 2- Delete a song from the directory 3- List all songs in the directory 4- Search a song: A – Search according to ID B – Search according to category 5- Update song information 6- Sort according to ID A - In ascending order B – In descending order 7- Sort according to category in alphabetic order 8- Quit struct date { int day, month, year; }; struct car { int ID; char songname[100], singersname[30], category[10]; struct date albumdate; }song_directory[100];
Problem 3. This problem is about the same file foo as in the previous problem, but before it is modified. A program opens it for reading and gets back the file descriptor number fd. The program has a character array char buf [30]. The program now does the following: if ((rv = read (fd, buf,20)) < 0) { ...handle error... } if ((rv = read(fd,buf,20)) < 0) { ...handle error...} a. What does each call return (assuming no errors)? b. What do the first 20 bytes of the character array buf contain after the second read call? c. What do the last 10 bytes of buf contain?
