In a loop, prompt the user to enter name data consisting of a first name, middle initial, last name, and employee number (type unsigned long). Then, using formatted I/O with the insertion (<<) operator, write these four data items to an ofstream object. Don’t forget that strings must be terminated with a space or other whitespace character. When the user indicates that no more name data will be entered, close the ofstream object, open an ifstream object, read and display all the data in the file, and terminate the program. solve it in oop c++

You have to read a file with 10 integers into an array named read_arr. Assume the file has been associated with the ifstream fin and num is a variable of integer data type. What will work? Group of answer choices (a) for(int i=0;i<10;++i)      read_arr[i]=(fin>>num); (b) for(int i=0;i<10;++i) {      fin>>num;      read_arr[i]=num; } (c) int i=0; while(fin>>num) {      read_arr[i]=num;      ++i; }   Both (b) and (c)   ===================== Which of the following is a correct struct declaration? Group of answer choices None of these struct Data { int id; float price; } Data struct { int id; float price; }  struct { int id; float price; } Data   ====================== Consider the following code fragment. struct Employer{     string name;    double salary;};void update (Employer emp){     emp.salary += 1000.00;}; int main(){     Employer e;     e.name = "Test"; e.salary = 1000;     update(e);     cout << e.salary;     return 0;}…

DescriptionWrite a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: each line contains a student's first name, then one space, then the student's last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The date in the output file will be nearly the same as the data in the input file except that you will print the names as last-name, first-name; each quiz score, and there will be one additional number at the end of each line:the average of the student's ten quiz scores.Both files are parameters. You can access the name of the input file with argv[1]. and the name of the output file with argv[2].The output file must be formatted as described below: 1. First and last names…
