Methods belong to classes, structs, and enums. Functions is just a code that can do a specific task and can be added to any file outside of a particular type.
In swift, a structure is defined is a single file so that it is less code for the programmer to type

Frontend development can be separated into two eras, before Bootstrap and after Bootstrap. In 2011, the greatest frontend framework ever was released. Also, in the same year, the adoption and use of the framework grew in great numbers, reaching almost every segment of the market.

Why do you think arrays in Swift only support a collection of objects of the same type?
If you create an array, and assign it to a variable, the collection that is created will be mutable. If you assign an array, its size and contents cannot be changed.

How can you access objects within an array one at a time?

going over arrays one element at a time is something that is a very common exercise , and to do that you’d run a counter over the length of the array and pick out each element one at a time.

How might you check if an array is empty?

to check if an array is empty, use Swift function "isEmpty" on the array. To check if an array is empty. The function returns a bool value. If the array is empty, "isEmpty" returns true, else false.

How does the contains function differ from the hasPrefix and hasSufix functions?

The HasPrefix and HasSufix functions work in the different way, the internal implementation just checks the length of both the strings and substring, and if the are = or the string is longer, then the required part of the string is compared

How is a method different from a property?

A property expresses an basic quality of an instance, while a method performs an action. Methods have parameters; properties don't. Prefer methods for any call with side effects. If a method does something (for example, it loads, parses, toggles, or prints) or has a verb name, it should not be a property.

2.What is the difference between a type and an instance?

Methods are functions that are associated with a particular type. Classes, structures, and enumerations can all define instance methods, which encapsulate specific tasks and functionality for working with an instance of a given type.

Module 3 Discussion

1- How is the number of columns in a web table determined?

The number of columns is based on the maximum number of cells from the table rows.

2- Write code to create a table row with three header cells containing the text: Tompkins, Ramirez, and David.

<.tr>
<.th>Tompkins
<.th>Ramirez

<.th>david
<./tr>

3- Write code to create a table row with three data cells containing the text: Tompkins, Ramirez, and David.

<.tr>
<.td>Tompkins
<.td>Ramirez
<.td>David
<./tr>

4- Write the style rule to display all table elements with collapsed borders.

table {border-collapse: collapse; }

5- Two table cells have adjacent borders. One cell has a 5-pixel-wide double border and the other cell has a 6-pixel-wide solid border. If the table borders are collapsed, what type of border will the two cells share?

The border will be a 6-pixle solid border because it is the border with the larger width.

6- A table data ell contains the text Monday and should stretch across two rows and three columns. Write the HTML code for the cell.

Monday

7-What adjustment do you have to make to a table when a cell spans multiple columns to keep the column aligned?

You need to reduce the number of cells following the spanning cell

8-What adjustment do you have to make to a table when a cell spans multiple rows to keep columns aligned?

You need to reduce the number of cells in the rows following the spanning cells

9-Write the style rule to display all table captions at the lower-left corner of the table.

caption { caption-side: bottom;}

Why do you think conditionals are important?
Sometimes you want code to execute only if a certain condition is true, and in Swift that is represented primarily by the if and else statements. You give Swift a condition to check, then a block of code to execute if that condition is true.

2. Give a set of instructions on how you think a thermostat program should work and “bold/underline” the conditionals.

functions in real life

Antonio — Thu, 16 Jan 2020 18:01:57 +0000

What processes and tasks, from real life, can fit into the various ways you can define a function? (Explain at least 5)

The function contains instructions used to create the output from its input. In that case, let's give 5 examples of real life situations that would mimic functions in coding.

1- Working out. A person needs to eat right, take whatever pre workout, that's the input, the out put would be, being more fit and building muscle

2- gaining weight. A person eats junk food, overloads on carbs and doesn't exercise, that's the intake. the outtake would be weight gain and poor health

3- driving a car. Person put gas into their car, that's the input. the output would be that the car drives without any issues. with this, the input needs the right kind of fuel. If you put water in the car, because it's the wrong input, then the output would be a not operational vehicle.

4- going to school. A person attended school to gain knowledge. So the intake is lecture, work and homework. The output is taking that knowledge and applying it to you job or life and understand what you are doing.

5- losing weight. A person limits the amount of carbs and sugars from their diet, so the outtake is less then the intake, so the person will loss weight.
