Question: Question #3: Write A C Program That Reads Integer Numbers From A Data File Name... Question #3: Write a C program that reads integer numbers from a data file named numbers.txt, one-by-one. For each number, the program computes and displays the factorial using: a user-defined function named factorial that you should declare and define in the program a user-defined function named factorial_ recursion that you should declare and define in the program The program writes the number and its factorial to a data file Results.txt. Hint: Function factorial has one argument: n (int) and returns n!. It uses for structure to compute n! Function power_ recursion is a recursive function that has one argument: n (int) and returns n!.

write you c++ code to read a file contains simple +/- maths equations and change it to plus and minus input file example: A+B, 10+20,30-50,8=100output file example A plus B , 10 Plus 20 , 30 minus 50 , 8 plus 100
Program in C only - thanks Write a C Program that writes all the numbers from 1 to 100,000 that are both prime and the sum of the digits > 9. For example 47, 911 are 2 such numbers, since the sum of the digits is > 9. After finding a number, you must immediately write it to the output file. Open the file, write the number you just found, and close the file. Measure how much elapsed time it takes to do this processing. Yes, it is inefficient, but we are trying to force some I/O usage, which will cause interrupts. When this process is completed, next have the program fork and create 10 separate processes. Each process would find search a range of 1 to 100,000 for these prime and sum 11 numbers. One process searches 1 to 10000, another 10001 to 20000 etc. Each process performs the exact same tasks , in the same way, as the first part of the problem, but write the output to 10 separate files, one for each process. When all 10 processes are done, read the ten files to make one file…
Q2: Write a c++ program that reads a text file that has a poem written in it. (Write down the poem yourself in a text file manually). Your program should display that poem and count a total number of lines in the file.
Write a program that reads the numbers from the file and displays their multiplication, yourprogram should prompt the user to enter a filename. Create such a file and check your code. solve with pyhton.
Answer the given question with a proper explanation and step-by-step solution. 1- Write code that does the following: opens an output file with the filename number_list.txt, uses a loop to write the numbers 1 through 100 to the file, then closes the file.
Write a program which reads from the keyboard the names of two files containing two doublenumbers. Your program should read these two values from the two files, compute their sum, dif-ference, product and division, and write the results on separate lines into the file “results.txt”.You can safely assume that the input is valid, the two input files exist and each contains one validdouble value.(please solve in C programming language).
In c++ write a code that tells a user to enter a filename and read that text file line by line.
Could you help me write a C++ code to do the following: Create a program that asks the user for the name of a file and thenrearranges the contents of the file so that its lines are in alphabetical order.The program should modify the file, not print its contents to the screen.Use the STL algorithm sort.
Write a C program which performs the following tasks:a. Create a Number.txt fileb. Write a program that prints x, x2(square) and x3(cube) in a file for x=1 to 10c. Close the file.d. Read Number.txt file and if any number is greater than 40 and odd, it should be ignored.e. Display the file contents on console
6.20 Word count (c++) Write a program that prompts the user to input the name of a text file and then outputs the number of words in the file. You can consider a "word" to be any text that is surrounded by whitespace (for example, a space, carriage return, newline) or borders the beginning or end of the file.Input Notes: There are two input sources in this program: the text file and standard input. The standard input consists of a single word, the name of the text file to be read. DO NOT USE A STRING VARIABLE.Output Notes (Prompts and Labels): The filename provided in standard input is prompted for with "Enter a file name: " and displayed so that the filename entered is on the same line as the prompt.The output of the program is a single line of the form: "The file contains N words." where N is the number of words determined by the program.
The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.
Write program that reads a list of names from a data file and displays the names to the console. The program should prompt the user to enter a filename. Create such a file and check your code. Solve with python. Example of code format: #Prompt the user for file name file_name = input("Enter file name : ") #Open file with open(file_name,"r") as file: #Read file content f = file.readline() #split the contents into numbers numbers = f.split(' ') test_list = [int(i) for i in numbers] res = 1 #Find the product for i in test_list: res*=i #Print result print("Product of numbers in the list :",res)
