Answer:

==

Explanation:

Operator precedence, it tells about the flow of operator execution o which operator execute first and which execute last.

'==' > '&&' > '||' > '='

According to precedence table,

the equal equal operator '==' comes first. so, it execute first and then NOT operator, then OR operator and finally equal operator.

The flow chart is a diagram that shows the activity of the program, peoples or things.

Flowchart symbol and meaning in the options:

1. Processing: it is a rectangular shape block which is used for variable declaration or assignment.

2. I/0: it is a parallelogram in shape which is used for input or output.

3. Parallelogram: it is used for input or output.

4. diamond: it is used for decisions or conditions.

Therefore, the correct option is a. Processing is the one that is used for the assignment statement.

Final answer:

In a flowchart, the symbol used for an assignment statement is a parallelogram, which is different from symbols used for processes (rectangles) or decisions (diamonds).

Explanation:

The symbol used for an assignment statement in a flowchart is a (c) parallelogram. This shape is typically used to represent input or output operations, which includes assigning values to variables. In a flowchart, various symbols are utilized to represent different types of actions or steps in a process.

For example, a rectangle is often used for process or operation symbols, and a diamond shape is used to denote decision points. However, when it comes to depicting the action of assigning a value to a variable, which is a fundamental step in many algorithms and programs, the parallelogram serves this purpose.

Answer: You must be careful to not touch the gold contacts at the bottom of the adapter because it might damage the device

Explanation: It is advised not touch the gold contacts of the adapter because that might damage the adapter by the oils present on the fingertips of a person which leads to corrosion at times and also there are chances of damage of the electronic component by the electrostatic discharge and that leads to the failure of the device .

Final answer:

To maintain electrical conductivity and prevent damage, avoid touching the gold contacts on adapters. Safety precautions and cleanliness are vital to protect the contacts from harmful materials. Preserving the integrity of the electrical connection is key to the proper functioning of the adapter.

Explanation:

It is crucial to be careful not to touch the gold contacts at the bottom of each adapter to prevent interference with electrical conductivity and avoid damaging the contacts. Gold is an excellent conductor of electricity, and touching the contacts with bare hands can introduce oils and dirt that may hinder the electrical connection.

Safety precautions such as wearing protective gear and ensuring clean hands are essential to prevent harmful materials from affecting the contacts and maintain the adapter's functionality.

Answer:

An assignment statement's overall syntax is-

                   variable = expression ;

Where the variable must be declared; the variable may be a simple name, or an indexed location in an array, or an object's field (instance variable) or a class static field; and the expression must result in a value that is compatible with the variable type. In other words, it must be feasible to cast the expression to the variable type.

Examples: int i =4;

a) b=(a+2);

(a+2) is the expression for adding 2 to a, whereas b equal to the result of (a+2).

b) a=b*4;

(b*4) is the expression for multiples b times 4,whereas a equal to the result of (b*4)

c) b=(a/3.14)

(a/3.14) is the expression for divides a by 3.14,whereas b equal to the result of (a/3.14)

d )a=(b-8)

(b-8) is the expression for Subtracts 8 from b,whereas a equal to the result of (b-8)

Answer:

The number of nodes in a full binary tree of height 2 = 7

Explanation:

At each level k, of the full binary tree there are usually [tex]2^{k} \\[/tex] nodes.

So the full binary tree of height 2 has nodes= [tex]2^{0} \\[/tex] + [tex]2^{1} \\[/tex] + [tex]2^{2} \\[/tex].

which is 7.

A full binary tree of height 2 consists of 7 nodes, including the root and two additional levels of nodes, with each level doubling the number of nodes from the previous level.

A full binary tree of height 2 has a total of 7 nodes. The definition of a full binary tree means that every node has 0 or 2 children. Given that the height (the longest path from the root to a leaf) is 2, this means there are 2 levels below the root. On level 1 (just below the root), there would be 2 nodes (since a full tree must have either 2 or 0 children). On level 2, each of those two nodes from level 1 would themselves have two children, adding 4 more nodes for a total of 6 nodes beneath the root. Including the root itself, which is level 0, brings the total number of nodes to 7.A full binary tree of height 2 has a root node connected to two child nodes, and each child node is connected to two more child nodes. So, the tree has a total of 7 nodes.

Answer:

srand(time(NULL));

int namesrand = rand() % 100 +1;

Explanation:

srand() is the function which is used for seeding the rand() function.

it defines the starting point different in whenever rand() function executes. Therefore, rand() generate the output different in every execution.

rand() is the function that generates the random number within the range.

for example;

rand() % 20

it generates the random number within the range [0,20).

NOTE: 20 not included in the range and zero is included.

similarly, generate the number between 0 to 99.

rand() % 100.

so, if we add the generated number by one then it ranges become 1 to 100 both included.

Answer:

Refresh rate means how many times the image on the screen is redrawn in a second.It is measured in hertz.

We can measure refresh rate of all of the devices listed in the question.

CRT Refresh rate measurement:-

The refresh rate can be measured by dividing the scanning rate by count of horizontal lines multiplied by 1.05.

Stereo Devices Refresh Rate measurement:-

When LCD's are used for stereo 3 D displays, the refresh rate is divided by 2, because we have two eyes and each one needs a distinct picture. For this reason,it is suggested to use a display of at least 120 Hz refresh rate, because on divided by 2 this rate is 60 Hz.For example 70 Hz non-stereo is 140 Hz stereo, and 80 Hz non-stereo is 160 Hz stereo.

LCD Refresh rate measurement:-

Refresh rate of a LCD is the number of times per second in which the data it is being redrawn by the display.

Answer:

A Red Black Tree is a type of self-balancing(BST) in this tree ,each node is red or black colored. The red black tree meets all the properties of the binary search tree, but some additional properties have been added to a Red Black Tree.

A Red-Black tree's height is O(Logn) where (n is the tree's amount of nodes).

In a red-black tree with black height k

The maximum number of internal nodes is [tex]2^{2k}[/tex] [tex]-1[/tex].

The smallest possible number is [tex]2^{k}[/tex] [tex]-1[/tex].

Final answer:

The largest possible number of internal nodes in a red-black tree with black height k is 2^(k+1) - 1, which assumes a completely filled tree. The smallest number of internal nodes is 2^k - 1, which represents a perfect black-height-balanced binary tree with no additional red nodes.

Explanation:

The largest possible number of internal nodes in a red-black tree with black height k is when each black node has the maximum number of children, which would be when both children are red. In this case, the maximum number of internal nodes is when we have a completely filled tree with alternating levels of red and black nodes, leading to a total of 2^(k+1) - 1 internal nodes, which includes both red and black nodes.

In contrast, the smallest possible number of internal nodes occurs when each black node has the minimum number of children, which is when it has two black child nodes or is a leaf node itself. In this scenario, the minimum number of internal nodes for a red-black tree with black height k is equal to the number of black nodes, which is 2^k - 1. This is because the tree would essentially be a perfect black-height-balanced binary tree without any additional red nodes.

Answer:In operating system,trap instruction is synchronous interrupt which arises due to occurrence of exceptional conditions.

Explanation:Trap instructions are the synchronous interrupt or exception . It may arise due to reasons like invalid memory access ,term division by zero etc. Trap instruction is a software invoked interrupt and it is type of a call which transfers the control synchronously. It is also a way of switching into the Kernel mode in which the operating system take some steps before returning the control to the main process  .

Answer:

D. related

Explanation:

A database is a collection of related data.

Answer:

A bool can hold only true or false values.

A char can hold maximum 65535 characters.

An int can hold maximum positive value of 2,147,483,647.

A float can hold maximum positive value of 3.4 x 10^{38}.

Explanation:

Primitive data types in Java language can be categorized into boolean and numeric data types.

Numeric can be divided further into floating point and integral type. Floating data type includes float and double values while and integral data type which consists of char, int, short, long and byte data types.

Every data type has a range of values it can hold, i.e., every data type has a minimum and maximum predefined value which it is allowed to hold. The intermediate values fall in the range of that particular data type.

Any value outside the range of that particular data type will not compile and an error message will be displayed.

The data types commonly used in programming are boolean, char, int and float.

A boolean variable can have only two values, true or false.

A char variable can hold from 0 to 65535 characters. Maximum, 65535 characters are allowed in a character variable. At the minimum, a char variable will have no characters or it will be a null char variable, having no value.

An int variable has the range from minimum -2^{31} to maximum 2^{31} – 1. Hence, the maximum positive value an int variable can hold is (2^{31}) – 1.

A float variable can hold minimum value of 1.4 x 10^{-45} and maximum positive value of 3.4 x 10^{38}.

The above description relates to the data types and their respective range of values in Java language.

The values for boolean variable remain the same across all programming languages.

The range of values for char, int and float data types are different in other languages.
