What is one example of an emerging class of software

Analyze the following code. Is count < 100 always true, always false, or sometimes true or sometimes false at Point A, Point

GaryK [48]

Answer:

Point A: Always True

Point B: Sometimes false

Point C: Always False

Explanation:

In the given code snippet. Point A is the first statement within the While loop the statement System.out.println("Welcome to Java!"); will only be executed if the while condition evaluates to true.

At Point B, The statement count++ increases the value of the counter at every iteration, while it will be true for most occasions, at the last increament, this statement will be false that is at count=100, The condition will be false at this point just before program execution breaks out of the loop

Point C is outside of the loop, this happens when the given condition is no longer true.

After the explosion of the Union Carbide plant the fire brigade began to spray a curtain of water in the air to knock down the c

AysviL [449]

Answer:

d. The system of water spray pipes did not have sufficient water supply

Explanation:

The Union Carbide India Ltd. was chemical factory situated at Bhopal that produces various pesticides, batteries, plastics, welding equipment, etc. The plant in Bhopal produces pesticides. In the year 1984, on the night of 2nd December, a devastating disaster occurred on the Bhopal plant which killed millions of people due to the leakage of the poisonous, methyl isocyanate. This disaster is known as Bhopal Gas tragedy.

Soon after the gas pipe exploded, the fire brigade started spraying water into the air to $\text{knock down}$ the cloud of the gases in the air but there was not sufficient amount of water in the water sprays and so it was not effective.

Thus the correct answer is option (d).

Declare a structure whose tag name is Server and that contains the following fields: manufacturer, a string, model and serialnum

NemiM [27]

Answer:

The answer to this question as follows :

Structure definition:

struct Server //define structure server.

{

string manufacturer;

//define string variable.

string model, serialnum; //define string variable.

int year;

//define integer variable.

double clockSpeed;

//define double variable.

int cores; //define integer variable.

int ram;

//define integer variable.

int storage;

//define integer variable.

};

Explanation:

Structure is a collection of heterogeneous(different type) elements. It is a user-define datatype which is available on the C/C++ programming language. To define any structure we use the struct keyword. The syntax of defining structure can be given as:

Syntax:

struct structure name

{

//define variables

//statements and code.

};

OR

struct structure name

{

//define variables

//statements and code.

}create structure variable;

In the above structure code, we define a structure that is "Server". In this structure, we define different types of variables that is " manufacturer, model, serialnum, year, clockSpeed, cores, ram, and storage". In this structure variable manufacturer, model and serialnum datatype are a string and clockSpeed datatype is double and variable year, cores, ram, and storage data type is an integer.

Hello again, just need help debugging-I honestly have no idea how the "isSpace" etc methods work and I've tried various syntaxes

Julli [10]

import java.util.Scanner;

public class JavaApplication81 {

public static void main(String[] args) {

Scanner s = new Scanner(System.in);

System.out.println("Input the string");

String as = s.nextLine();

int cons = 0;

int a = 0;

int e = 0;

int i = 0;

int o = 0;

int u = 0;

int space = 0;

int punc = 0;

char c;

int misc = 0;

String punctuation = ".!,?";

String consonants = "bcdfghjklmnpqrstvwxyz";

for (int k = 0; k < as.length(); k++){

c = as.charAt(k);

if (Character.isWhitespace(c)){

space ++;

}

else if (punctuation.indexOf(c) != -1){

punc++;

}

else if (consonants.indexOf(c) != -1){

cons++;

}

else if (c == 'a'){

a++;

}

else if(c == 'e'){

e++;

}

else if (c == 'i'){

i++;

}

else if (c == 'o'){

o++;

}

else if (c == 'u'){

u++;

}

else{

misc++;

}

System.out.println(a+" a's");

System.out.println(e+" e's");

System.out.println(i+" i's");

System.out.println(o+" o's");

System.out.println(u+" u's");

System.out.println(space+" spaces");

System.out.println(punc+" punctuations");

System.out.println(cons+" consonants");

System.out.println(misc+" misc. (uppercase vowels, etc.");

}

This is one example of how it could be done.

Which of the following statements is TRUE? C++ functions can return a value of type array if it is returned as a base address va

lesantik [10]

Answer:

The answer to this question is "C++ functions can't return array type value".

Explanation:

In C++ language the method is a collection of declarations executing a process together. It is a statement, that tells the compiler to return and accept parameters of a function. In C++, it includes many standardized functions, which can be called by the software, and other choices were wrong, which can be described as follows:

In c++ function can't return array type always.
function is not address based.
If array is local to function, but function will not return array value.
