Under which of the following conditions will evaluating this boolean expression

1 answer:

3 0

1.)
((i <= n) && (a[i] == 0)) || (((i >= n) && (a[i-1] == 0))) 

The expression will be true IF the first part is true, or if the first part is false and the second part is true. This is because || uses "short circuit" evaluation. If the first term is true, then the second term is *never even evaluated*. 

For || the expression is true if *either* part is true, and for && the expression is true only if *both* parts are true. 

a.) (i <= n) || (i >= n) 

This means that either, or both, of these terms is true. This isn't sufficient to make the original term true. 

b.) (a[i] == 0) && (a[i-1] == 0) 

This means that both of these terms are true. We substitute. 

((i <= n) && true) || (((i >= n) && true)) 

Remember that && is true only if both parts are true. So if you have x && true, then the truth depends entirely on x. Thus x && true is the same as just x. The above predicate reduces to: 

(i <= n) || (i >= n) 

This is clearly always true.

Answer:

The explanation for this question is describes in the explanation section below.

Explanation:

A palindrome is a number, string, expression or certain character pattern that appears the very same backward as a forward.

Below is an algorithm for the series:

Step 1: Creates an object of generic stack-type of string set.

Step 2: Accept the sequence from those in the user as its entry.

Step 3: Throughout the specified set, disregard the white space.

Step 4: Build an object for the reverse string to be stored.

Step 5: To store the stack into the string, place the object that has come into the stack.

Step 6: Test whether the reversed string equals the initial string.

Step 7: Display the message of success.

Step 8: Display the message of failure when the strings aren't the same.

OS(The Operating System) sends interrupts to the processor to stop whatever is being processing at that moment and computer architecture send data bus. This bus sends data between the processor,the memory and the input/output unit.

The operating system is a low-level software that supports a computer’s basic functions, such as scheduling tasks and controlling peripherals while the computer architecture has the address bus bar. This bus carries signals related to addresses between the processor and the memory.

The interface between a computer’s hardware and its software is its Architecture while An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs.

Explanation:

In short explanation,the Computer Architecture specifically deals with whatever that's going on in the hardware part of the computer system while the Operating System is the computer program which has been program to execute at some instances depending on the programming instructions embedded in it.
