a.
- Include library files for various operations.
- Declare object ofofstream.
- Create a statement to open the write data to the file “employee.dat”.
- Use if statement with fail() method to check that the entered file name is available or not.
- int main() function is used to perform all the task.
- Display the calculated results to the user.
Program Description: The main purpose of the program is to create a text file, “employee.dat” and to write the given data to the file.
b.
Program Plan:
- Include library files for various operations.
- Declare objects ofifstream and ofstream.
- Declare required variable.
- Create two statements to open “employee.dat” and “employee.bak” file.
- Use if statement with fail() method to check that the entered file name is available or not.
- int main() function is used to perform all the task.
- Display the calculated results to the user.
Program Description: The main purpose of the program is to modify the program code of part (a) so that the program code can create a duplicate copy of the text file with the name “employee.bak”, that contains all the data of “employee.dat” file.
c.
Program Plan:
- Include library files for various operations.
- Declare objects ofifstream and ofstream.
- Declare required variable.
- Read file names from the user.
- Create two statements to open “employee.dat” and “employee.bak” file.
- Use if statement with fail() method to check that the entered file name is available or not.
- int main() function is used to perform all the task.
- Display the calculated results to the user.
Program Description: The main purpose of the program is to modify the program code of part (b)so that the program code will read the name of the original and duplicate file from the user, creates a duplicate copy of the text file with name “employee.bak”, that contains all the data of “employee.dat” file.
d.
To find the better method for accepting the original and duplicate filenames in the program.

Solve the problem by hand on paper only and upload a photo of your handwritten solution."arrow_forwardSpecifications: Part-1Part-1: DescriptionIn this part of the lab you will build a single operation ALU. This ALU will implement a bitwise left rotation. Forthis lab assignment you are not allowed to use Digital's Arithmetic components.IF YOU ARE FOUND USING THEM, YOU WILL RECEIVE A ZERO FOR LAB2!The ALU you will be implementing consists of two 4-bit inputs (named inA and inB) and one 4-bit output (named out). Your ALU must rotate the bits in inA by the amount given by inB (i.e. 0-15).Part-1: User InterfaceYou are provided an interface file lab2_part1.dig; start Part-1 from this file.NOTE: You are not permitted to edit the content inside the dotted lines rectangle. Part-1: ExampleIn the figure above, the input values that we have selected to test are inA = {inA_3, inA_2, inA_1, inA_0} = {0, 1, 0,0} and inB = {inB_3, inB_2, inB_1, inB_0} = {0, 0, 1, 0}. Therefore, we must rotate the bus 0100 bitwise left by00102, or 2 in base 10, to get {0, 0, 0, 1}. Please note that a rotation left is…arrow_forward
