Four types of mandatory parameters: 1. Value: declared without any modifiers 2. Ref: ref modifier 3. Out: out modifier 4. Param: declared with the params modifier
REF&OUT:
Advantage: method can change multiple variables
Disadvantage: they allow multiple methods to have access to the same data
Parameter array: Local array declared within the method header by using the keyword params. Only one param keyboard is permitted in a method declaration
Week 3
Overloading:
Involves using one term to indicate diverse meanings
When you overload a c# method, you can write multiple methods with a shared name. The compiler understands your meaning based on the arguments you use with the methods
Methods are overloaded correctly when they have the same identifier but difference parameter lists
Overloaded only means that you have more than one method signature
Ex: DisplayWithBorder (int) and DisplayWithBorder (string)
Overload resolution: determines which method to execute when a method call could execute multiple overloaded methods
Applicable methods: a set of methods that can accept a call with a specific list of arguments
Betterness rules: that determine which method version to call
Ambiguous methods: a situation which the compiler cannot tell which method to use. Occurs when you overload a method ex simplemethod (inum, inum); // error! Call is ambiguous
Optional parameter: only value params can be given default values. All optional parameters in a list must follow all mandatory parameters. Ex displaySize (int length, int width, int height = 1); must have all optional values in the end. Can have all optionals, can have all required.
Ex. Method1(int a, char b, int c= 22, double d = 33.2)
Int char int double
Creating objects: declaring a class does not create any actual objects. When you create an object, you call its constructor. An object is a reference type.

...1. How has Islam shaped conceptions of music for the peoples of the Middle East? In the Middle East, Islam is not just a religion; it is a way of life. Islam’s influence spread in the Middle East music conceptions. For example, the Arabic scale is strongly melodic, based around various maqamat or modes. Also, Mann explains that “under the wide rule of Islam, vulgar lyrics and suggestive dancing by women became illegal. Much post-Islamic music is used in ceremonial dance and recreation. (Mann)” In the Middle East, people may hear their songs of praise and prayer. The “World Music: A global Journey, says that “in addition to being suspicious of the sensual aspects of music Islamic aesthetics frowns on realistic representation in art, especially of the human form, to avoid the temptation toward idol worship. But as with sound, it may not always be obvious to outsiders what is considered art and what is not. (Miller 255)” Because, the influence of Islam has had great impact on people related with music, and people used to meditation, trance, and self-flagellation with one’s a higher sense of God while listening music. 2. What is modal improvisation? Is it primarily a compositional or a freely expressive form of performance? According to Henry, modal improvisation is that “a typical modal tune may have only two or three chords, and each may last 8 or even 16 measures. In one sense, modal playing is much easier than playing changes, since it does not require your brain to do as...

...* Dayani Herrera * Week 2 Assignment The Chain of Custody Process Limiting Access to the Evidence * When a piece of evidence is collected, there are numerous individuals who will have access to it before the case goes to trial. The investigator, evidence technician,
property officer, laboratory technician, prosecutor and defense attorney all may have custody. Each individual in this chain has a responsibility for the safe-keeping and preservation of the evidence while it is in their possession.

 Initial Collection * Before any evidence is removed from the crime scene, there should be an evidence custodian designated as the person in charge of initiating and maintaining all evidence. This person needs to document the crime scene location, as well as his time of arrival. There should also be a crime scene log established, witness list and documentation of identification, arrival and departure times of all law enforcement crime scene personnel.

 Record Keeping * The investigator who handles the evidence initially should affix her name, badge number and assignment to the package containing the evidence. When the evidence leaves the officer's possession, a record should be made in her case notes identifying to whom the evidence was given, the date and time, and the reason it was turned over. A signed receipt should be obtained from the person accepting the evidence and another signed receipt should be obtained when the item is returned. When the item...

...Designing Parallel Programs Automatic vs Manuel Parallelization - Very often, manually developing parallel codes is a: Time Consuming Complex Error-prone and Iterative Process - The most commonn type of tool used to automatically parallelize a serial program is a parallelizing compiler or pre-processor. - A parallelizing compiler generally works in two different ways: A. Fully Automatic - The compiler analyzes the source code and identifies opportunities for parallelism. - The analysis includes identifying inhibitors to parallelism and possibly a cost weighting on whether or not the parallelism would actually improve performance. - Loops (do,for) are the most frequent target for automatic parallelization. B. Programmer Directed - Using "compiler directives" or possibly compiler flags, the programmer explicitly tells the compiler how to parallelize the code. - May be able to be used in conjunction with some degree of automatic parallelization also. - The most common compiler generated parallelization is done using on-node shared memory and threads (such as OpenMP). Caveats (warning/caution) that apply to automatic parallelization: 1. Wrong results may be produced. 2. Performance may actually degrade. 3. Much less flexible than manual parallelization. 4. Limited to a subset (mostly loops) of code. 5. May actually not parallelize code if the compiler analysis suggests there are inhibitors or the code is too complex. Understand the...

...My thoughts about Grandma Mary, the epitome of love. I want to say to you all the things I wish I’d said to my other loved ones who left too soon, before I could make sure to tell them all they meant to me. Grandma Mary, you are one of a kind. Your life is a reminder of the best attributes of the people who built our great country, an example for those who will come after you. You’re a reminder of the virtues that matter, a precious treasure to all who know you. Though you’d be quick to remind me you’re not perfect and have your human faults, it could not diminish all the wonderful things you are. Godly Beautiful Thankful Wise Tender Loving Giving Frugal Fun Good Precious Caring Kind Dignified Polite Unselfish Tough Laughter Commitment Honest Devotion Independent Faithful I wrote this when we were visiting you and I showed it to Tina, I was just trying to list all the fruits of the spirit that you have so consistently demonstrated with your beautiful life. Now I realized I never shared it with you, so here it is… I love you, Grandma. I never really had a Grandma growing up, as my my Mom’s mother died when I was young, and my father’s mother had dementia by the time I was a teenager, and even the childhood years only hold a few memories of her. I was the middle child of eight children, so there was a lot of competition to get attention from adults, and I never imagined having a Grandma like you, who always has a hug and a kiss, along with gentle...

...Requirements for Project. A company produces three types of switches – S1, S2, and S3 – and supplies them to a retailer. It is contractually obligated to meet the demands of the retailer for each type of switch. Because of limited capacity the company may not have sufficient machining, assembly, and finishing time available to satisfy the entire demand in each period through in-house production alone. Contractual obligation requires the company to make up the shortfall in production by procuring it from an external supplier at higher costs. The company aims to meet the retailer’s demands at minimum cost. LP Formulation: Task 1: Formulate a linear programming (LP) model that may be solved to identify the optimal production and procurement plan for the company in each time period. | Specifically, you must define the decision variables, objective function, and constraints in your LP model using the following parameters: In each time period, for each product i∈(1, 2, 3): * Di is the demand (number of units required) for product i. * CiP is the cost (in dollars) for producing each unit of product i. * CiS is the cost (in dollars) for procuring each unit of product i from the external supplier. * tim is the machining time (in minutes) required to produce each unit of product i. * tia is the assembly time (in minutes) required to produce each unit of product i. * tif is the finishing time (in minutes) required to produce each unit of product...
