A(n) ________decision is a decision in which at least one of two conditions must be true for an action to take place. Boolean expressions are named after_____________.
When you nest decisions because the resulting action requires that two conditions are true?
1. When you nest decisions because the resulting action requires that two conditions be true, either decision logically can be made first and the same selections will occur .
When you need to satisfy two or more criteria to initiate?
When you need to satisfy two or more criteria to initiate an event in a program, you must make sure that the second decision is made entirely independently of the first decision . Any decision can be made using combinations of just two types of comparisons: equal and not equal.
When you combine AND and OR operators the ____ operators take precedence meaning their Boolean values are evaluated first group of answer choices?
When you combine AND and OR operators, the OR operators take precedence, meaning their Boolean values are evaluated first. You use the case structure only when a series of decisions is based on a single expression.
What operator is used to reverse the meaning of a Boolean expression?
Negation is a process of reversing the meaning of a boolean expression. There are two approaches used to negate the Boolean expression. The first approach is the easiest one. Just use a NOT operator in front of the original Boolean expression and your negated Boolean expression is ready.
When you have a five element array and use subscript 6 your subscript is said to be out of bounds?
When you have a five element array and use subscript 6, your subscript is said to be out of bounds. You can either increment or decrement the loop control variable. You can improve the efficiency of a program by leaving a loop as soon as a match is found in the array.
What are the 4 Boolean operators?
Boolean Operators are simple words ( AND, OR, NOT or AND NOT ) used as conjunctions to combine or exclude keywords in a search, resulting in more focused and productive results.
What is the best strategy for avoiding off by one errors?
The code snippet will display the desired result. What is the best strategy for avoiding off-by-one errors? Think through a couple of test cases and use the results to come up with a rationale for decisions .
What is ?: operator called?
In computer programming, ?: is a ternary operator that is part of the syntax for basic conditional expressions in several programming languages. It is commonly referred to as the conditional operator, inline if (iif), or ternary if.
Which operator is used to compare two values?
The equality operator (==) is used to compare two values or expressions. It is used to compare numbers, strings, Boolean values, variables, objects, arrays, or functions.
Which expression evaluates true?
A boolean expression is an expression that evaluates to a boolean value. The equality operator, == , compares two values and produces a boolean value related to whether the two values are equal to one another. In the first statement, the two operands are equal, so the expression evaluates to True .
What are DeMorgan’s theorems?
De Morgan’s Theorem, T12, is a particularly powerful tool in digital design. The theorem explains that the complement of the product of all the terms is equal to the sum of the complement of each term . Likewise, the complement of the sum of all the terms is equal to the product of the complement of each term.
Can hold the size of an array?
By default, the maximum size of an Array is 2 gigabytes (GB) . In a 64-bit environment, you can avoid the size restriction by setting the enabled attribute of the gcAllowVeryLargeObjects configuration element to true in the run-time environment. However, the array will still be limited to a total of 4 billion elements.
Is not lost when a computer loses power?
Data is not lost when a computer loses power, and it is referred to as nonvolatile . This is similar to a program saving data on to a disk. in a computer system. They exist on permanent storage devices.
Is a program or class that instantiates objects of another prewritten class?
| A B | class client or class user A program or class that instantiates objects of another prewritten class | class header or class definition Describes a class; it contains an optional access modifier, the keyword class, and any legal identifier for the name of the class |
|---|
What is boolean example?
A Boolean expression is any expression that has a Boolean value. For example, the comparisons 3 < 5, x < 5, x < y and Age < 16 are Boolean expressions. The comparison 3 < 5 will always give the result true, because 3 is always less than 5.
