Tutorial 3 case study

Operations on Vectors We look at some of the basic operations that you can perform on lists of numbers. It is assumed that you know how to enter data or read data files which is covered in the first chapter, and you know about the basic data types. Most of the basic operations will act on a whole vector and can be used to quickly perform a large number of calculations with a single command. There is one thing to note, if you perform an operation on more than one vector it is often necessary that the vectors all contain the same number of entries.

You don't have to reset it for each line. However, I have a trick question for you. What happens if you change the field separator while reading a line? That is, suppose you had the following line One Two: However, if you deleted the first print statement, it would print out "Three" once!

I thought this was very strange at first, but after pulling out some hair, kicking the deck, and yelling at muself and everyone who had anything to do with the development of UNIX, it is intuitively obvious. You just have to be thinking like a professional programmer to realize it is intuitive.

I shall explain, and prevent you from causing yourself physical harm. If you change the field separator before you read the line, the change affects what you read.

If you change it after you read the line, it will not redefine the variables. You wouldn't want a variable to change on you as a side-effect of another action.

A programming language with hidden side effects is broken, and should not be trusted. AWK allows you to redefine the field separator either before or after you read the line, and does the right thing each time.

Once you read the variable, the variable will not change unless you change it. To illustrate this further, here is another version of the previous code that changes the field separator dynamically.

When the line contains a colon, the field separator is a colon, otherwise, it is a space. Here is a version that worked with older versions of awk: In the first case, the two positional parameters are concatenated together and output without a space.

In the second case, AWK prints two fields, and places the output field separator between them. Normally this is a space, but you can change this by modifying the variable "OFS".

If you wanted to copy the password file, but delete the encrypted password, you could use AWK: You can make the output field separator any number of characters.

You are not limited to a single character.Describe the three different categories of cognitive biases and discuss how they may have affected Bill's ability to make effective decisions on the night of the lightning strike in the case study.

Be sure to give examples from the case study. Cases and Casebooks - a Brief History. Briefing a case is simply the act of creating a "brief" summary of the relevant facts, issues, rule and reasoning of a particular case you've read in class. However, to understand briefing, you must first understand the case method, which is how most law schools teach rutadeltambor.com at Harvard University Professor Christopher Columbus Langdell decided.
