Modify task5.c so it will print out a content of a file backward. You will need to use lseek() to accomplish this task.  Modify this program to print the file backward. */ #include #include #include int main(int argc, char *argv[]) {     char *filename = argv[1];         int input = open(filename, O_RDONLY);         char c;         while(1){                 int r = read(input,&c,1);                 if(r==0)                         break;                 write(1,&c, 1);         }     close(input);         return 0; }

USING C++ PLEASE CREATE THREE FILES! IntCollection.h (or IntCollection.hpp): class definition IntCollection.cpp: class implementation main.cpp, including sample output and your answer to question 6 at the bottom. : main program to run the code The following code creates an IntCollection object named ‘c’. It adds seven integers to ‘c’, then uses a for loop to display the seven integers: int main() { IntCollection c; c.add(45); c.add(-210); c.add(77); c.add(2); c.add(-21); c.add(42); c.add(7); for (int i = 0; i < c.getSize(); i++) { cout << c.get(i) << endl; } } For this assignment you will add a copy constructor, a destructor, and three overloaded operators to the IntCollection class. In the design diagram below, the black member functions represent code that has already been implemented. You will be implementing the green items. Each item that you will be adding to the class is described below the diagram. private: int size // the number of ints currently stored in…

Write a program in C++ that creates a file. Write this  data into that file column wise as a header. Then keep adding data in colum wise format. The program should check if there is data in the file and then write the data in the next row.  First add:  TIME            DAY          MONTH         YEAR Then check the file and add: 01:25            07             JUNE             2008 Then check again the file and add this in next row: 14:00            30             MARCH         2019

Java Your program must read a file called personin.txt.  Each line of the file will be a person's name, the time they arrived at the professor's office, and the amount of time they want to meet with the professor.  These entries will be sorted by the time the person arrived.   Your program must then print out a schedule for the day, printing each person's arrival, and printing when each person goes in to meet with the professor.  You need to print the events in order of the time they happen.  In other words, your output will be sorted by the arrival times and the times the person goes into the professor's office. In your output you need to print out a schedule.  In the schedule, new students go to the end of the line.  Whenever the professor is free, the professor will either meet with the first person in line, or meet with the first person in line if nobody is waiting.  Assume no two people arrive at the same time. You should solve this problem using a stack and a queue. You can only…
