Write a C program that reads real numbers from a data file named "numbers.txt", one-by-one. For each number, the program checks whether the number is positive or negative, and writes only the positive numbers to a text file named "result.txt". The program must use the necessary code to handle File not found/not created errors. Below are examples of the input and output files 3.14 -25.5 -22.7 10.25 20.0 -18.2 3.14 10.25 20.0 numbers.txt Results.txt

Write a C program that, given a text file, constructs Huffman code based on the character frequencies of the file and then encodes the file accordingly. The executable must accept the following command line options:• -i filename for the input file • -o filename for the output file Use the fread function, use FILE, size, etc. Please use the following to write the code: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <getopt.h>
Write a C++ program that counts the number of non white-space characters in an input text file. Program takes as command argument(s) the name of the input file (and the output file with option -f). Based on the option flags, it displays the output on the standard output, or writes the output to an output file. The command format is as follows:command -f inputfile outputfile or, command -s inputfile -f indicates writing to an output file;-s indicates displaying the output on the screen. Also notice the errors caused by incomplete arguments. Including: (1) The name of the author of the program (your name) and the date it was written, (2) a concise description of what the program does, (3) a clear description of its limitations if it does not meet all specifications, and (4) explanation for critical code and data declarations. The same should also be done for each function written in the program.
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).
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.
Write a C program named toupper.c that reads the contents of a file, and writes to another file after changing all lowercase letters in the input file to uppercase. The name of the input file and the output file are to be passed as command line arguments. Assume there are only ASCII characters in the input file. The length of the input file is not known beforehand. So make sure your program keeps reading bytes until EOF is reached. Use the library function toupper to concert letters into uppercase. Example: The program is run from the command line as follows; C:\>toupper.exe infile.txt outfile.txt Suppose the contents of the input file infile.txt is: AbcdefG The contents of the output file outfile.txt should be: ABCDEFG
Consider a file named transaction.txt which contains unknown number of lines. Each line contains data of one transaction as follows: username (string), amount (float), and membership number (int). Write a C++ program that reads the data from the file, then displays on screen the number of users, the total amount, the average of amounts, the lowest amount and the highest amount. Reading from the file should stop when one or more of the conditions given below becomes true:(a) The end of file has been reached. (b) The “user999” is reached.

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…
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.
Write a Program in CWrite a c program that counts the number of words and characters in a file. The program should do the following: Asks the user to input the name of the file to be opened.
