A field is a single attribute of an entity, object or event.
Answer:
ii. break
Explanation:
In Computer programming, a loop can be defined as a sequence of instructions that are executed repeatedly until a specific condition is true or for a certain number of times.
This ultimately implies that, a loop is a programming structure that continually repeats a sequence of instructions until a specific condition is true (met) or for a definite number of times.
Basically, there are three (3) main types of loop in programming and these includes;
I. For loop.
II. While loop.
III. Repeat.
Since loops continually repeats a sequence of instructions until a specific condition is true (met), it is a best practice to ensure that the loop breaks at some point to avoid an infinite loop. An infinite loop typically causes a software program to crash.
Thus, the break command is used by programmers to prevent an infinite loop or terminate a current loop immediately.
Hence, the command to get out of the loop is break.
Answer:
(A) Always true
<em></em>
Explanation:
Given
Boolean variables x and y
Required
What is (x && y) || !(x && y)
Irrespective of what x or y is, the x && y is always true
Take for instance:
<em>x = true;</em>
<em>y = true;</em>
<em>x&&y will also be true because the values of x and y were not altered</em>
<em />
<em>And this is true for whatever boolean value x or y assume</em>
<em />
Having said that:
x&&y = true
So, the expression is analysed as follows:
(x && y) || !(x && y)
Substitute true for x&&y
(true) || !(true)
<em>!(true) = false</em>
So, the expression becomes:
true || false
|| represents the OR operator; and it returns true if at least one of the conditions is true.
By this:
true || false = true
<em>Option (A) Always true </em><em>answers the question.</em>
Answer:
For a computer to function properly, it must consist of both hardware and software, because the hardware and software are interdependent.
Explanation:
This means that the one will not function without the other. Hardware consists of the physical components of a computer, also referred to as the equipment of a computer
