Answer:

D. keep your hand and forearm in the same plane

Explanation:

The ergonomic principle explains how to maintain a good posture. And if hands and forearms are in the same plane then you will do least work, and hence not loss more energy, which you can lose if your elbows are close together while typing or your hand and forearm is not in the same plane, or your hands are crossed, or your neck is non aligned to your spines. And if you want to work more efficiently in your office, then you should study ergonomic principles certainly.

Which type of app is the best choice when it is critical to be able to use the device's features but performance is not critical

lisov135 [29]

Answer:

Hybrid.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem.

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are seven (7) main stages in the creation of a software and these are; planning, analysis, design, development (coding), testing, implementation and execution, and maintenance.

Some of the models used in the software development life cycle (SDLC) are;

I. A waterfall model: it can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.

II. An incremental model: it refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.

III. A spiral model: it can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.

Basically, softwares are categorized into three (3) main categories based on the development platform and these are;

a. Web application.

b. Native application.

c. Hybrid application.

A hybrid application is a type of software application that is designed based on the combination of the elements of both web applications and native applications.

Typically, a hybrid application is a web application that is developed in a native application shell, using a standardized web programming language such as CSS, JavaScript, and HTML.

Generally, a hybrid application avails a programmer the opportunity to write a code for a mobile application once while accommodating or being compatible with multiple app platforms such as Android, Windows, iOS, etc.

Hence, a hybrid application is the best choice of an application when it's critical for the end users to be able to use the features associated with a device such as a mobile phone but performance isn't critical.

What are the two access modes that are used when opening a file for input and output when pickling?

san4es73 [151]

The two access modes that are used when opening a file for input and output when pickling are rb and wb.

<h3>What is pickling?</h3>

Pickle is generally used in Python to serialize and deserialize a Python object structure. In other words, it is the act of transforming a Python object into a byte stream in order to save it to a file/database, maintain program state across sessions, or transport data over a network. By unpickling the pickled byte stream, the original object hierarchy can be recreated. This entire procedure is comparable to object serialization in Java or .Net.

When a byte stream is unpickled, the pickle module first makes an instance of the original object before populating it with the right data. To accomplish this, the byte stream only carries data relevant to the original object instance.

(1) Prompt the user for a string that contains two strings separated by a comma. (1 pt) Examples of strings that can be accepted

denis-greek [22]

Answer:

Check the explanation

Explanation:

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

#define MAX_LIMIT 50

int checkComma(char *input)

{

int flag = 0;

for(int i = 0; i < strlen(input); i++)

{

if(input[i] == ',')

{

flag = 1;

break;

}

return flag;

}

int main(void)

{

char input[MAX_LIMIT];

char *words[2];

char delim[] = ", ";

printf("\n");

{

printf("Enter input string: ");

fgets(input, MAX_LIMIT, stdin);

size_t ln = strlen(input) - 1;

if (*input && input[ln] == '\n')

input[ln] = '\0';

if(strcmp(input, "q") == 0)

{

printf("Thank you...Exiting\n\n");

exit(1);

}

else

{

if(checkComma(input) == 0)

{

printf("No comma in string.\n\n");

}

else

{

char *ptr = strtok(input, delim);

int count = 0;

while(ptr != NULL)

{

words[count++] = ptr;

ptr = strtok(NULL, delim);

}

printf("First word: %s\n", words[0]);

printf("Second word: %s\n\n", words[1]);

}

}while(strcmp(input, "q") != 0);

return 0;

}
