When a function template has two parameterized types, one as the return value, and one as an argument, then THE FIRST TIME MUST BE EXPLICITLY CODED.

Explanation:

The act of implicit and explicit coding, and implicit and explicit code, is defined by context of execution of additional behavior or type setting/casting. Specifically, implicit or explicit methods are defined by the contexts in which they are meant to be used.
The explicit coding discipline favors clear and explicit expression of intent in the code.
The uses-cases dictate the structure of the application. What the application does should not be implicitly hidden in an organization that the framework is trying to dictate you. Avoid having folders like /controllers, /views at the highest level of folders organization, in favor of folders containing features and use-cases: /categories, /products, etc.
Template parameter represents a type that has not yet been specified, but that can be used in the template function as if it were a regular type.

Discuss some design considerations that you should keep in mind when you want to design a professional-looking flyer or newslett

Korvikt [17]

A designer should always balance the placement of text and graphics and create room for every element to breathe. When this is followed, the flyer template will create a feeling of balance and calm.

Consider adding a border: Borders can help your flyer or newsletter stand out wherever it is placed. Selection of certain colors, Italics and ALL CAPS can draw attention to particular points in a text.

Boost contrast with style, color and font size: Always use font weight to differentiate sections of text. Many fonts offer regular, bold and light options for font weight.

Align text for a balanced look: A designer should consider using a grid system that contains intersecting vertical and horizontal lines that are often based on optimal proportions for the document’s size. Aligning text in the center will give a pleasant symmetrical look.

Kruka [31]

A Peer-to-peer network architecture would work best for Edward and Matthew.

Although they have the option of creating a Client-Server type of network architecture, the number of people that they are currently working with would cost them a lot more than a peer-to-peer architecture.

One of the advantages of using a Peer-to-peer network architecture for a small network would be the access of files between all computers in the network. Even if one of the computers will fail, the other computers will still have access to the different files and information they will need to keep the company moving forward.

Just a quick question, how do you set something == to char and int in an if statement (java)

Troyanec [42]

This is the requested code in java.

public class CharTest {

public static String checkCharacter(String text, int index) {

if (0 <= index && index <= text.length()) {

char ch = text.charAt(index);

if (Character.isLetter(ch)) {

return ch + " is a letter";

} else if (Character.isDigit(ch)) {

return ch + " is a digit";

} else if (Character.isWhitespace(ch)) {

return ch + " is a whitespace character";

} else {

return ch + " is an unknown type of character";

}

} else {

return "index " + index.toString() + " is out of range";

} // end if

} // end function checkChar()

public static void main(String[] args) {

// Test the three samples from the specification.

System.out.println(checkCharacter("happy birthday", 2));

System.out.println(checkCharacter("happy birthday", 5));

System.out.println(checkCharacter("happy birthday 2 you", 15));

} // end function main()

} // end class CharTest

The function checkcharacter(text, index) returns a string value describing the kind of character found at the position in text specified by index; whether it was a letter, digit, whitespace, or an unknown kind of character.

How it does that is to make use of respective functions defined within the Character class in java. That is

isLetter(char) returns a bool specifying if the char parameter is a letter.

isDigit(char) returns a bool specifying if the char parameter is a digit.

isWhitespace(char) returns a bool specifying if the char parameter is a whitespace character.

It calls these functions in an if statement. These else part of the if statement is then executed if the character is neither a letter, digit, or whitespace.

Finally, the function main() calls checkCharacter() three times to test the function and return the results to the console.
