Determine The First Two Lines Of The New File Created By The Code Be

1. Determine the first two lines of the new file created by the code below. This exercise refers to the file Justices.txt that contains data about the Supreme Court justices, past and present. Each record contains six fields – first name, last name, appointing president, home state, year appointed, and year they left the court. If they are still on the court, the last field is set to 0.

The first two lines of the file are as follows: Samuel, Alito, George W. Bush, NJ, 2006, 0

Henry, Baldwin, Andrew Jackson, PA, 1844

Dim query = From line In IO.File.ReadAllLines("Justices.txt")

  Let data = line.Split(",")

  Let firstName = data(0)

  Let lastName = data(1)

  Let fullName = firstName & " " & lastName

  Let state = data(3)

  Select fullName & "’" & state

IO.File.WriteAllLines("NewFile.txt", query)

Paper For Above instruction

This code reads data from the file "Justices.txt", processes each line to extract the first name, last name, and state of each justice, then constructs a string combining the full name and state for each justice. It finally writes the collection of these strings into a new file called "NewFile.txt".

The first two lines of the output file "NewFile.txt" would mimic the first two entries from "Justices.txt", formatted as concatenation of the full name and the state. Given the example data, the first two lines are:

  • Samuel Alito NJ
  • Henry Baldwin PA

These lines indicate the full names of the justices followed by their home states, separated by spaces, as per the format constructed by the code.

Additional details:

The logic reads each line, splits it into parts, and then constructs a string with full name and state. The first two entries from "Justices.txt" are therefore reproduced as their full names followed by the respective state abbreviations, aligned with the format of the LINQ query.

Understanding the code’s effect:

The code performs a LINQ query over all lines, transforming each record into a string of full name and state, then writes all these strings to "NewFile.txt". Therefore, the first two lines in the output file correspond exactly to the first two records in the input, formatted as specified.

Conclusion:

Based on the provided data, the first two lines of "NewFile.txt" are:

Samuel Alito NJ

Henry Baldwin PA
