Answer:

break

Explanation:

Break is the statement in the programming which is used to terminate the loop or case in the switch structure.

Break immediately terminate or move program control to next statement outside the loop or switch structure.

For example:

for(int i=0;i<4;i++)

{

   print("hello world");

   break;

}

when the program execution reach to the break statement. The loop structure terminate and program control goes to next of for loop.

similarly for switch case,

switch(int number)

{

case 1:

         print("hello");

         break;

}

when the program execution reach to the break statement. it terminate the switch structure.

Answer:

Answer is (d) value of 10

Explanation:

Usually when we write "int x=10;", a memory space is allocated for an integer variable with name x, and content 10.

Answer:

Option d is the correct answer for the above question.

Explanation:

In c,c++ or java programming language, when a user declares a variable then that means that a variable is used to take space in memory and When a user assigns the value on that variable then that value is stored on the location of variable in the memory and that variable addressed that value for compiler and memory.

The above question asked that if there are declaration and initialization of a variable then what is held by the variable in the memory. The answer is the value which stated by Option d, hence it is a correct option while other is not because--

Answer:

3 3

Explanation:

The operator modulus '%' is gives the reminder of the number.

for example:

7%2  it gives the result 1 because 1 is reminder after divided by 2.

Initially the value of funny is 7 and serious is 15.

then, 15 is modulus by 2 which gives 1 and it store in the funny.

After that, if else statement check for condition.  

funny != 1  this condition is FALSE because Funny is equal to 1.

it moves to else if part Funny == 2 condition again FALSE it then move to else part and execute the statement Funny contain 3 and serious contain 3.

and then display.

Therefore, the answer 3 3.

Explanation:

Answer:

UTF-8 and ASCII both are the character encoding.

In a system,every character has some binary representation,these are the method to encode them.Earlier only ASCII was there, for every character it uses 8 bits to represent.In ASCII only 8 bytes were there i.e 2^8 that is 256.We can't represent number beyond than 127 so it generate a need for other encoding to get into,these drawbacks lead to Unicode,UTF-8.

As ASCII codes only uses a single byte,UTF-8 uses upto 6 bytes to represent the characters.So we can save characters which are as long as 2^48 characters. We can read this encoding easily by the help of shift operators and it is also independent of byte order.

As messages on internet were transferred over 7 bit ASCII messages,so many mail servers removed this encoding.    

Final answer:

UTF-8 offers greater language support and compatibility with ASCII, making it ideal for international applications, at the expense of potentially increased file size and complexity in encoding/decoding processes.

Explanation:

Advantages and Disadvantages of UTF-8 Compared to ASCII

The question regarding the advantages and disadvantages of UTF-8 compared to ASCII centers on two dominant character encoding schemes used in computers and digital devices. ASCII, which stands for American Standard Code for Information Interchange, was one of the first encoding standards to be widely used. UTF-8 (8-bit Unicode Transformation Format) is a more modern encoding scheme designed to address some limitations of ASCII.

Advantages of UTF-8

Compatibility with ASCII: UTF-8 is backward compatible with ASCII. This means that any ASCII text is also valid UTF-8 text, facilitating a seamless transition between the two.

Global language support: Unlike ASCII, which only supports English characters, UTF-8 can represent characters from virtually any language in the world, making it ideal for international applications.

Dynamic character size: UTF-8 encodes characters using 1 to 4 bytes, efficiently representing more characters than ASCII without using extra space for simpler characters.

Disadvantages of UTF-8

Potential for increased file size: For languages that predominantly use characters outside the ASCII range, UTF-8 encoded files may be larger than those encoded in a fixed-width format designed for that language.

Complexity: Decoding and encoding UTF-8 can be more complex than ASCII, requiring additional processing power, which might be a consideration for systems with limited resources.

In summary, UTF-8 offers greater flexibility and language support compared to ASCII but may introduce complexity and increased file size for certain languages. Its design balances compatibility with the need for a universal encoding system that accommodates the global nature of the internet and computing.

Answer:

The correct answer is A. People that are likely to exhibit violent behavior on the job are associated with neurotic personality.

Explanation:

Neurosis or neuroticism is a psychological tendency to maintain certain difficulties for emotional control and management.

People with high levels of neuroticism usually have low moods, close to depression or dysthymia, and show negative feelings such as envy, anger, anxiety and guilt. Neurotic people present this symptomatology much more frequently and severe than people who do not suffer from this condition.

The personality characteristic that is associated with people who have the tendency to display violent behavior on the job is: a. Neurotic.

Neurotic is a term used to described someone that is afflicted by neurosis. It implies a drastic and irrational mental, emotional or psychical reactions that are often out of proportion towards a minor problem.

We can create headers in  html using <h1> through <h6> tags

Explanation:

We have six types of headings. They are:

<h1>

<h2>

<h3>

<h4>

<h5>

<h6>

If we want the heading to mark it as an important one, we can use <h1>.

So, <h1> heading is used for main headings.

If we want the heading to mark it as a least important one, we can use <h6>.

<h3>, <h4>, <h5> are used for sub headings.

Each HTML heading has a default size. However, you can specify the size for any heading with the style attribute, using the CSS font-size property as shown below:

    <h1 style="font-size:50px;">The Hindu</h1>

We use headings to show the document structure.

Here is a simple html code :

<!DOCTYPE html>

<html>

<body>

<h1 style="font-size:50px;">This is my heading</h1>

<p> some text here</p>

Explanation:

We can deduce from the formula that any result from a positive integer for n will be divisible by 2, because of the following facts.

If n is an odd number, then n+5 will equal an even number. Also since an even number multiplied by an odd number equals an even number it is thereby divisible by 2.

Example: 3(3+5) ⇒ 3(8) = 24 (divisible by 2)

If n is an even number, then n+5 will equal an odd number, and as stated above any integer multiplied by an even number will equal an even number thus making it divisible by 2.

Example: 2(2+5) ⇒ 2(7) = 14 (divisible by 2)

   float radius,length;

   float bottom_area, area, volume;

   cout<<"Enter the value of Radius: ";

   cin>>radius;

   cout<<"\nEnter the value of length: ";

   cin>>length;

   bottom_area = radius * radius * 3.14;

   area = bottom_area * length;

   volume = (2 * radius * 3.14 * length) + (2 * bottom_area);

   cout<<"Area is: "<<area<<endl;

   cout<<"Volume is: "<<volume<<endl;

}

Explanation:

First include the library iostream for input/output.

then, initialize the variable radius and length.

cout is used to print the message or result on the screen

cin is used to store the value in the variable.

after that, by using the formula calculate the area and volume of cylinder.

the result is store in the area and volume variable.

Finally, print the result the output on the screen.

Note:  All variables declare in the code is float type means you can enter the decimal value but you can enter the integer as well.

Final answer:

To calculate the area and volume of a cylinder, you input the radius and length, then use geometric formulas to calculate the bottom area, cylinder volume, and cylinder surface area. A sample Python program was provided to perform these calculations and display the results.

Explanation:

To compute the area and volume of a cylinder, we first need to gather input for the cylinder's radius (r) and length (h), which is often referred to as the height of the cylinder. We then apply the following formulas:

Here is a program in Python that performs these calculations:

Remember to use consistent units for radius and length, such as meters or centimeters.

Answer:

A) A virtual image cannot be formed on a screen.

Explanation:

A virtual image cannot be formed on a screen is correct about images.

A virtual image can be viewed by the unaided eye.

A virtual image can be photographed.

Mirrors don't always produce real images.

The correct statement about images is that a virtual image cannot be formed on a screen, as virtual images are created by diverging light rays. However, they can still be seen and photographed because devices like cameras and the human eye can focus these rays.

The correct statement about images is A) A virtual image cannot be formed on a screen. Virtual images are formed when light rays diverge in front of a mirror or behind a lens, creating an image that appears to be located behind the mirror or lens. Unlike real images, which can be projected onto a screen because they are formed by converging light rays, virtual images are not formed at a point in space where a screen can capture them. However, virtual images can be seen by the unaided eye and can also be photographed, contrary to some misconceptions. This is because cameras and eyes can focus diverging rays to form an image.
