Solved in 2 steps
- C++ Write a code segment that creates an ofstream object named outfile, opens a file named numfile.txt, and associates it with outfile. Then write the contents of the variable data to the file, followed by a newline, then close the file.F1(a1, b1, t1); F1(int a1, double &b1, double t10); 1 Poir Question 10 Suppose you have an open file object called infile. Which of the following C++ statements will close the file? A infile.close(); close("infile"); (C infile.closeFile(); closeFile("infile"); pinutes remaining DELLProgramming language : C++ 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.
- Files Class Activity Write a program to write your first name (hard coded) to the screen and possibly to a file whose name is passed into the program from the command line. It can be written in upper or lower case or mixed case as the default. Usage: writer [-f filename] If the -f option is included with a filename, then create a file with that name or overwrite a previously existing file and write your name in on the first line. If the -f option is not included, then only write your name to the screen followed by a newline. Use a copy of the original getopt to parse the command line. Be sure to test whether a file open succeeds or not and close any file you open when done.String data type is not allowed you can make use of CString instead (char arrays with null termination). Write a menu driven C++ program to perform the following four tasks in a single file, if user press option 1 the task 1 get solved and so on: 1. Display the Item_Id of the products which are not available in stock on screen. 2. Copy all the available products data in a separate file. 3. Read the original input file and update the price of each item by 10 percent increase in the original price and save the complete information in separate file. 4. Try to save the information processed in part 3 in the original file by updating it instead of using separate file.In c++ write a code that tells a user to enter a filename and read that text file line by line.
- C++ do not use chegg Write a program that reads from a text file named “sales.txt”, which contains the sales figures (double) of a store. Your program should: Display the average, the highest, and the lowest sales figures Remember to: Test the file open error Close the file at the end. text file 284.12223.09579.12998.651237.84764.75395.65458.01670.353765.003842.10190.23335.35662.952719.253564.02193.23222.231457.2089.751323.65234.35789.89224.67663.95245.38<<Write in Java>> - Challenge 7 File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code. Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file. - Challenge 8 Write a program that decrypts the file produced by the program in Programming Challenge 7. The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another fileQ3:IN SML language how would I write a string to integer function that inputs a filename and returns zero if the contents inside the file is blank.
- please code in pythonredact_file: This function takes a string filename. It writes a new file that has the same contentsas the argument, except that all of the phone numbers are redacted. Assume that the filename has onlyone period in it. The new filename is the same as the original with '_redacted' added before theperiod. For instance, if the input filename were 'myfile.txt', the output filename would be'myfile_redacted.txt'. Make sure you close your output file.The first hard task in this function is to make the output filename from the input filename that waspassed in. You can break it into two pieces by splitting on the dot or by using the index method andslicing. Then put it back together again using string concatenation.We are also working with files in this one. To open a file with a filename stored in the variable fname,in read mode use the open function as such: fp = open(fname). You will need to open the outputfile in write mode: open(fname, 'w'). Then you can traverse 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 PROGRAMMINGIn C++ code: Design and write a C++ class that reads text, binary and csv files. The class functions: Size: Returns the file sizeName: Returns the file nameRaw: Returns the unparsed raw dataParse: A external function to Parse the data. The function accepts the raw data and returns the data parsed by the function. This type of function is called a "Call-Back Function". A Call-Back is necessary for each file as each file requires different regular expressions to parse. Call-back.cpp #include <string>#include <functional>#include <iostream>#include <vector>using namespace std; string ToLower(string s){ string temp; for (char c : s) temp.push_back(tolower(c)); temp.push_back(NULL); return temp;} string ToUpper(string s){ string temp; for (char c : s) temp.push_back(toupper(c)); temp.push_back(NULL); return temp;} struct Append{ string operator()(string a, string b) // function object { return a…
