Answer:
The statements which are true are;
- A user-defined data type can include other user-defined data types
- A user-defined data type is defined using a class
- A user-defined data type can include a list
Explanation:
A user-defined data type (UDT) is a datatype that is defined and derived by the use of the datatypes which preexist including existing user-defined datatypes and the built-in datatypes
It is therefore true that a user-defined data type can include other user-defined data types
A class is a user-defined data type that contains both its member data and member functions, that can be used when an instance of the class is first created
Therefore, a user-defined data type is defined using a class
In a user-defined data type, a variable has actual data within it which can include an array or list
Therefore a user-defined data type can include a list.
Answer:
C. Accept the risk
Explanation:
The first option is close but might not be suitable for a small company considering it's cost.
The second option which is to spend fifty thousand dollars per year on a data loss prevention solution is projected to cost you more than the risk.
The third option isn't specific and lacks a course of action.
Here is an HTML example with the CSS class defined inline:
<!doctype html>
<html>
<head>
<style>
.YellowBackground {
background-color : yellow;
}
</style>
</head>
<body class="YellowBackground">
<h1>A yellow background</h1>
</body>
</html>
Answer:
Top down design
Explanation:
Top-down design is an approach that is used to break down the problem into the smaller subpart so that it can be manageable into more clear form.
C programming is the example of a top-down approach while C++ is the example of the bottom-up approach.
The advantages of the top-down design approach are:
1) easy to manage
2) easy to find the error
3) easy to debug
Answer:
public static void quad(double a, double b, double c) {
double D = (Math.pow(b, 2)) - (4 * a * c);
if (D<0){
System.out.println("no real solutions");
}
}
Explanation:
The code snippet above implements the function in Java programming language
As required by the question, the line double D = (Math.pow(b, 2)) - (4 * a * c); evaluates b squared" - 4ac and assignes the value to the variable D
An if statement is used to test if D is less than 0, if this is true the message no real solutions is printed
