Given the int variables x, y, and z, write a fragment of code that assigns the smallest of x, y, and z to another int variable m

Marysya12 [62]

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

int x=5,y=2,z=9;

int min;

// find the smallest value and assign to min

// if x is smallest

if(x < y && x < z)

// assign x to min

min=x;

// if y is smallest

else if(y < z)

// assign y to min

min=y;

// if z is smallest

else

// assign z to min

min=z;

// print the smallest

cout<<"smallest value is:"<<min<<endl;

return 0;

}

Explanation:

Declare and initialize variables x=5,y=2 and z=9.Then check if x is less than y and x is less than z, assign value of x to variable "min" .Else if value of y is less than value of z then smallest value is y, assign value of y to "min".Else z will be the smallest value, assign its value to "min".

Output:

smallest value is:2

A teacher wants a program to give extra points to students who fail a test. Write a Python program to do the following: (a) Ask

Lorico [155]

Answer:

Hi there! Please find the answer below.

Explanation:

The program below demonstrates how each of the requirements can be coded in a simple Python script. To copy the array, we can use the copy() method of the array. To calculate the diff, we can use a few different techniques, so I have implemented it using a loop over the arrays and just storing and displaying the difference in the 2 arrays.

new_string.py

def add_test_score(score):

test_score.append(score);

contact_hash = {}

test_score = []

print("Enter 5 test scores: ");

for x in range(0, 5):

input_string = input("Enter test score " + str(x + 1) + ": ")

add_test_score(int(input_string));

print(test_score);

test_score_copy = test_score.copy();

for e in test_score_copy:

if e < 60:

test_score_copy[test_score_copy.index(e)] += 10;

diff = [];

for e in test_score:

print(test_score[test_score.index(e)]);

print(test_score_copy[test_score.index(e)]);

if not test_score[test_score.index(e)] == test_score_copy[test_score.index(e)]:

diff.append(e);

print(diff);

2. Consider a 2 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of

allsm [11]

Answer:

program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

Explanation:

Finding number of instructions in A and B using time taken by the original processor :

The clock speed of the original processor is 2 GHz.

which means each clock takes, 1/clockspeed

= 1 / 2GH = 0.5ns

Now, the CPI for this processor is 1.5 for both programs A and B. therefore each instruction takes 1.5 clock cycles.

Let's say there are n instructions in each program.

therefore time taken to execute n instructions

= n * CPI * cycletime = n * 1.5 * 0.5ns

from the question, each program takes 1 sec to execute in the original processor.

therefore

n * 1.5 * 0.5ns = 1sec

n = 1.3333 * 10^9

So, number of instructions in each program is 1.3333 * 10^9

the new processor :

The cycle time for the new processor is 0.6 ns.

Time taken by program A = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.1 * 0.6ns

= 0.88 sec

Time taken by program B = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.4 * 0.6

= 1.12 sec

Now, program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

A network of Bennetton retail sales agents select the Bennetton designs that they feel will appeal to Bennetton retail customers

denpristay [2]

Answer:

It is an example of a matrix structure

Explanation:

The matrix structure is a structure in which jurisdiction, controls and duties are carried and uphold by a group of employees instead of just the manager.

In other words, employees have dual reporting relationships; they can give reports to the functional manager and they can also give reports to the product manager.

The Bennetton design selected by the network of Bennetton retail sales agents made activities to be easily coordinated because, they have collectively performed the duty as a unit and this is one of the advantages of this form of the matrix organizational structure.

Explain the difference between using the int type and the double type for numbers.

MaRussiya [10]

They have different semantics, addition to having different semantics from double, int arithmetic is generally faster, and the smaller size (32 bits vs. 64 bits) leads to more efficient use of caches and data transfer bandwidth.....
