- SUBJECT NAME IS C++: WAP to read 4 student objects and write them into a file, then print total number of student number in file. After that read an integer and print details of student stored at this number in the file using random access and file manipulatorsIn C++, write a program that creates a file in C and appends the following details from the user: Student Number: Name: Course: Age: Note: Use struct to store the input values from the user and same struct be used to append its values to the created file.In 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…

Create a .cshrc file in your home directory that will do the following: * Create the alias (lsall) that will do all of the following: display the date, and a recursive long list of all files in a directory. * Create the alias (whoson) that will display the date and a sorted list of users logged in. * Declare the LOCAL variable that controls the size of your history list to the value 200. * Declare the shell variable that will cause the C Shell to send a message to your terminal whenever one of your background commands complete. 2. Create a .login file in your home directory to do the following. * Declare the GLOBAL Terminal Type variable to the value vt100. Display the value of the variable. Logout and log back in to make sure your .cshrc and .login files are automatically executed. Create a lab8.scr…/** * The file path that is IOManager read and write an object from.

In another function called check_password, the function must ask the user to input the password to login and it should match the password in the file. If it doesn't, it should keep asking the user to keep inputting the right password. Finally, just by passing in the two functions into the main, that would be fine. Ex. int main() { ....password(....); ....check_password(....); }
- 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…File redirection allows you to redirect standard input (keyboard) and instead read from a file specified at the command prompt. It requires the use of the < operator (e.g. java MyProgram < input_file.txt) True or FalseIn C++, Query the user for the name of a file. Read the words from the file and report the number of words whose last letter is 'a', the number whose last letter is 'b' and so on, irrespective of case.
- What will the following code print assuming infile is a file object that has been just opened for reading in the preceding step? infile.readline() lines = infile.readlines() print(lines[0]) O Print the second line of the file. O Print the third line of the file. O Print the first line of the file. O Print all the lines of the file.TRUE FALSE The dereference operator * is used to obtain the address of a variable. The void functions return noting when called. the flag eof() is FALSE at the beginning of a text file. There is no way to show text on graphic screen The reserved word struct is used when declaring a void function.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
