A:
1. Create a text file called “input.txt”, which contains N values (N is unknown). Write a C++
in an array.
Step by step
Solved in 3 steps with 1 images
- Task 1. Create a C file and declare declare the following variables in your main function: char string1[12] = "hello"; char string2[12] = "hello\n"; char string3[12] = "hello\n\0you\n"; char string4[12] = "0123456789AB"; The first function that we will write is the void printArray(char a[], int length) function. It has an array of characters as input and an integer that indicates the length of the array. void signifies that it has no return value. The function prints the '[' character and then all characters in the array, separated by commas, finally followed by the ']' and '\n' characters. When a character in the string is null then you should print \0, i.e. the backslash character followed by ’0’. When a character in the string is the newline character then you should print \n, i.e. the backslash character followed by ’n’. Call printArray with each of the string variables as input. The output should be as follows: [h,e,l,l,o,\0,\0,\0,\0,\0,\0,\0] [h,e,l,l,o,\n,\0,\0,\0,\0,\0,\0]…Write a program in C++ to do the following: 2. Create an array to hold up to 20 integers. 3. Create a data file or download attached text file (twenty_numbers.txt) thatcontains UP TO 20 integers.4. Request the input and output file names from the user. Open the filesbeing sure to check the file state.5. Request from the user HOW MANY numbers to read from the data file,up to twenty. Request the number until the user enters 20 or less, but not lessthan 0. The user enters the number of integers to read. The integers are storedin the file and are to be read from the file.6. Write a function that reads from the opened data file: the numberof integers the user wants to read, and store the numbers inthe array. For example, if the user wants to read 13 numbers,read 13 of the 20 that may be in the file.7. Write a function that writes to the opened output file AND THECONSOLE, the numbers stored in the array.8. NO GLOBAL variables are to be used. The input and output file variablesmust be passed…(a) Write a C function readNums() that takes a filename and an integer array, reads the integer numbers in the file and stores into the array, returns the number of numbers stored in the array. Assume that the file only contains integer numbers, and nothing else. Prototype: int readNums(char filename[], int arr[]); (b) Write a C function delWordN() that takes a string and an integer (n) as parameter, removes from the string the words that are n character long. A word is a group of consecutive alphanumeric characters; words are separated by non-alphanumeric characters. ps: please do not copy paste from chegg or anywhere else. write unique code
- Write a C++ program that requests the user to enter 10 floating-point values. The first 5values are stored in the array A, while the next 5 values are stored in array B. Then, calculate C = A + B, where C is an array. Write the result in a file in the following format:Ci = Ai + BiIn C++ Ask the user for three friends names, store the names in an array. Output the array to a file called FRIENDS.2. Write a C program called writer.c. It uses system call I/O to create a file called list1.txt which has the following text-based content: 101 GM Buick 2010 102 Ford Lincoln 2005 There are three blanks between the first and the second columns. There is one tab between the second and third, and between the third and fourth columns. You can only call function “write” once. After file list1.txt is created, type the following commands to check the content of the file.
- 1. a) Write a program to create two files with the names file4.txt and file4a.txt two 10 element int arrays with the names arrfile4 and arrfile4a; these arrays are to have different values write the contents of arrfile4 to file4.txt write the contents of arrfile4a to file4a.txt b. Modify exampleFour to read integer values from the keyboard, store them into a 15 element array, then write the array into a file named userin.txt exampleFour In the while loop, this program reads fileLoop.txt until all items are read; Each item in the file is stored into an array package storeintoarr; import java.util.Scanner; import java.io.*; public class Storeintoarr { public static void main(String[] args) throws IOException { File loopfile = new File("fileLoop.txt"); Scanner getAll = new Scanner( loopfile ); // connect a Scanner to the file int num = 0, square = 0; int[] items = new int[10]; int i = 0;…write a function called fillArrayFromFilethat will read numbers from a file that contains one double per line into an array(up to the size of the array) and then returns the number of doubles successfully readfrom the file. You may assume that the file contains valid doublesYou are creating a function that reads a data file and prints each line of the file. You write the following code. Line numbers are included for reference only The code attempts to read the file even if the file does not exist. SEE PHOTO You need to correct the code. Which three lines have indentation problems? Each correct answer presents part of the solution. (Choose three.) Group of answer choices Line 04 Line 03 Line 05 Line 02 Line 06 Line 07 Line 01 Line 08
- Please help with C++, CANNOT use array or vector CAN ONLY USE BELOW #include<iostream> #include<fstream> #include<string> #include<iomanip> This program numbers the lines found in a text file. (text file name is story.txt) Write a program that reads text from a file and outputs each line to the screen and to another file preceded (preceding file name outputfile.txt) by a line number. Print the line number at the start of the line and right-adjusted in a field of three spaces. Follow the line number with a colon, then one space, then the text of the line. You should get a character at a time and write code to ignore leading blanks on each line. You may assume that the lines are short enough to fit within a line on the screen. Otherwise, allow default printer or screen output behavior if the line is too long (that is, wrap or truncate). A somewhat harder version determines the number of spaces needed in the field for the line numbers by counting lines before…PYTHON-Assume you have a file that has two columns separated by a comma. The first column contains gene accession numbers, and the second column contain their nucleotide sequence. For example: ABC123, AAGTCTTCCCTAAGCCC... KHJ456, TTCGGTCATACTATTC... NMG789, GCTACTCGATGCTA.... .... The file can contain any number of rows. Write a program that reads in this file (you can create one to test your code with, use TextEdit or Notepad) and creates a dictionary, where the keys are the accession numbers and the values are the sequences. Print out to the screen the dictionary pairs that you created.Part 1: Write a C/C++ language program that creates an array of 10,000 random unsigned integers in the range 1 to 1,000,000. These integers are then stored in a text file called numbers.txt Part 2: Write a C/C++ language program that reads the file numbers.txt and checks each number for being a prime number. Only the prime numbers from these are then written to a text file prime.txt. Part 3: Modify the program of part 2 so that it takes an input argument num_jobs with a value between 1 and 8. E.g. if num_jobs is 3, it splits into 3 parallel processes using fork() function, and each process then calculates prime numbers from a subset of the input data. Together these 3 jobs find prime numbers from all the 10,000 input integers. The overall parent process then combines the results from its children into a single file prime.txt Part 4: Calculate the times taken by running the program of part 3, and make a table where the time taken for calculation is given for each value of num_jobs from…
