Write a program that asks the user to enter the size of a triangle (an integer from 1 to 50). Display the triangle by writing lines of asterisks. The first line will have one asterisk, the next two, and so on, with each line having one more asterisk than the previous line, up to the number entered by the user. On the next line write one fewer asterisk and continue by decreasing the number of asterisks by 1 for each successive line until only one asterisk is displayed. (Hint: Use nested for loops; the outside loop controls the number of lines to write, and the inside loop controls the number of asterisks to display on a line.) For example, if the user enters 3, the output would be:_______.a. *b. **c. ***d. **e. *

Consider the following functions: (4) int hidden(int num1, int num2) { if (num1 > 20) num1 = num2 / 10; else if (num2 > 20) num2 = num1 / 20; else return num1 - num2; return num1 * num2; } int compute(int one, int two) { int secret = one; for (int i = one + 1; i <= two % 2; i++) secret = secret + i * i; return secret; } What is the output of each of the following program segments? a. cout << hidden(15, 10) << endl; b. cout << compute(3, 9) << endl; c. cout << hidden(30, 20) << " " << compute(10, hidden(30, 20)) << endl; d. x = 2; y = 8; cout << compute(y, x) << endl;

Answers

Answer:

a.  cout<<hidden(15,10)<<endl;

output = 5

b. cout << compute(3, 9) << endl;

output=3

c. cout << hidden(30, 20) << " " << compute(10, hidden(30, 20)) << endl;

output = 10

d. x = 2; y = 8; cout << compute(y, x) << endl;

output= 8

Explanation:

solution a:

num1= 15;

num2= 10;

according to condition 1, num1 is not greater than 20. In condition 2, num2 is also not greater than 20.

so,

the solution is

return num1 - num2 = 15 - 10 = 5

So the output for the above function is 5.

solution b:

as in function there are two  integer type variables named as one and two. values of variables in given part are:

one = 3

two = 9

secret = one = 3

for (int i= one + 1 = 3+1 = 4; i<=9%2=1; i++ )

9%2 mean find the remainder for 9 dividing by 2 that is 1.

//  there 4 is not less than equal to  1 so loop condition will be false and loop will terminate. statement in loop will not be executed.

So the answer will be return from function compute is

return secret ;

secret = 3;

so answer return from the function is 3.

solution c:

As variables in first function are num1 and num2. the values given in part c are:

num1 = 30;

num2= 20;

According to first condition num1=30>20, So,

num1= num2/10

so the solution is

num1 = 20/10 = 2

now

num1=2

now the value return from function Hidden is,

return num1*num2 = 2* 20 = 40

Now use the value return from function hidden in function compute as

compute(10, hidden(30, 20))

as the value return from hidden(30, 20) = 40

so, compute function becomes

compute(10, 40)

Now variable in compute function are named as one and two, so the values are

one= 10;

two = 40;

as

secret = one

so

secret = 10;

for (int i= one + 1 = 10+1 = 11; i<=40%2=0; i++ )

40%2 mean find the remainder for 40 dividing by 2 that is 0.

//  there 11 is not less than equal to  0 so loop condition will be false and loop will terminate. statement in loop will not be executed.

So the answer will be return from function compute is

return secret ;

secret = 10;

so answer return from the function is 10.

solution d:

Now variable in compute function are named as one and two, so the values are

one = y = 8

two = x = 2

There

Secret = one = 8;

So

for (int i= one + 1 = 8+1 = 9; i<=2%2=0; i++ )

2%2 mean find the remainder for 2 dividing by 2 that is 0.

//  there 9 is not less than equal to  0 so loop condition will be false and loop will terminate. statement in loop will not be executed.

So the answer will be return from function compute is

return secret ;

secret = 8;

so answer return from the function is 8.

as a technician, you have been tasked with increasing the ram memory on a laptop by adding a so-dimm module to an empty memory slot. which of the following processes seats the module in the slot?

Answers

As a technician, since you have been tasked with increasing the ram memory on a laptop by adding a so-dimm module to an empty memory slot. The process that seats the module in the slot is option D:

  • Align the notch on the long side of the memory module with the rise in the memory slot. Insert the module pins into the slot at a 45-degree angle. Rotate the module by pressing down until the side hold-down clips snap into place.

Why is a laptop so quick?

The processor, RAM, and computer memory all have an impact on how quickly your laptop operates. The pace increases as each number increases. For example, 4GB of RAM operates more quickly than 2GB. A 2 GHz machine will operate more quickly than a 1 GHz one since processor speed is measured in gigahertz.

Therefore, One application may run on this much memory. If your computer only has 4 GB of RAM, upgrading it would significantly enhance performance. 4-6 GB: The typical user's chores, including as web browsing, working with Word documents, and emailing, will be easily handled by this normal RAM amount.

Assume you have a system where you need to maintain operability even during the failing, replacing, and rebuilding of a failed disk. Thus, the data in the failed disk must be rebuilt and written to the replacement disk while the system is in operation. Which of the RAID levels yields the least amount of interference between the rebuild and ongoing disk accesses?

Answers

Answer:

RAID level 1 fits the criteria to yield the least amount of interference between the rebuild and ongoing disk accesses.

Explanation:

RAID system can be defined as the process in which hard drives which are connected to the system are been set up in order to help speed up the performance of a computer system disk storage which is why RAID is mostly used on servers and high performance computers system . This RAID as well helps to combines multiple physical disk drive components into various logical units for the aim of increasing system performance.

Therefore RAID level 1 fits the criteria to yield the least amount of interference between the rebuild and ongoing disk accesses. This is because the level 1 of RAID copies just the data from the failed Systems disk mirror during the rebuilding period where as the other levels of RAID copies the whole lot of content of the other disks due to the fact that RAID 1 often requires at least minimum of two physical drives because data is written simultaneously to two places in which the drives are essentially mirror images of one another in which if one fails, the other one can take over and help to provide access to the data that is been stored on that drive.

Which Numpy function do you use to create an array? (Points : 1) npnp.array
np.numpy
numpy

Answers

Answer:

The correct option is np.array

Explanation:

Numpy is a library to perform numerical calculation in python. It allows us to create and modify vectors, and make operations on them easily. Numpy arrays are an excellent alternative to python lists. Some of the key advantages of numpy arrays are that they are fast, easy to work with, and offer users the opportunity to perform calculations through full arrays.

To start using numpy, the library must be imported:

import numpy as np

The most common way to create a vector or matrix already initialized is with the np.array function, which takes a list (or list of lists) as a parameter and returns a numpy matrix. The numpy arrays are static and homogeneous typing. They are more efficient in the use of memory.

Example:

list = [25,12,15,66,12.5]

v = np.array (list)

print (v)

(Numerical Data Representation) How many bits per word are required to represent the following positive decimal integers: a.0 through 100b.0 through 255c.0 through 256d.0 through 10,000,000

Answers

Answer:

a. 7 bits

b. 8 bits

c. 9 bits

d. 24 bits

Explanation:

Required

Number of bits per word

The formula to get the number of bits per word is:

2^n = N

Where

n = bits

N = numbers

Solving (a) 0 to 100

There are 101 digits between 0 and 100 (inclusive)

So:

N = 101

Substitute 101 for N in 2^n = N

2^n = 101

101 can not be expressed as an exponent of 2.

So, we substitute 101 for the closest number greater than 101 that can be expressed as an exponent of 2.

So:

2^n = 128

Express 128 as an exponent of 2

2^n = 2^7

Apply law of indices

n = 7

Hence, 7 bits are required

Solving (b): 0 through 255

There are 256 digits between 0 and 255 (inclusive)

So:

N = 256

Substitute 256 for N in 2^n = N

2^n = 256

Express 256 as an exponent of 2

2^n = 2^8

Apply law of indices

n = 8

Hence, 8 bits are required

Solving (c): 0 through 256

There are 257 digits between 0 and 256 (inclusive)

So:

N = 257

Substitute 257 for N in 2^n = N

2^n = 257

257 can not be expressed as an exponent of 2.

So, we substitute 257 for the closest number greater than 101 that can be expressed as an exponent of 2.

So:

2^n = 512

Express 512 as an exponent of 2

2^n = 2^9

Apply law of indices

n = 9

Hence, 9 bits are required

Solving (d): 0 through 10000000

There are 10000001 digits between 0 and 10000000 (inclusive)

So:

N = 10000000

Substitute 10000000 for N in 2^n = N

2^n = 10000000

10000000 can not be expressed as an exponent of 2.

So, we substitute 10000000 for the closest number greater than 101 that can be expressed as an exponent of 2.

So:

2^n = 16777216

Express 16777216  as an exponent of 2

2^n = 2^{24

Apply law of indices

n = 24

Hence, 24 bits are required
