Answer:

The answer is letter D.

Explanation:

The progam will never leave the loop body.  Because a loop consists of two parts, a body of a loop and a control statement. The control statement is a combination of some conditions that direct the body of the loop to execute until the specified condition becomes false.

The loop that does not stop executing and processes that statements number of times is called an infinite loop or endless loop.

-Dominant- [34]

Answer:

The answer is "True".

Explanation:

Integration control is a system selection, which is important to ensure the proper coordination of the different components of the programs. Analogies between conflicting goals and solutions must be made to meet or surpass the needs and wishes of participant groups. This mechanisms use events for identifying, defining, combining, unifying and coordinating software development procedures and events, that's why the given statement is true.

Complete function PrintPopcornTime(), with int parameter bagOunces, and void return type. If bagOunces is less than 3, print "To
SVETLANKA909090 [29]

Answer:

<h2>Function 1:</h2>

#include <stdio.h> //for using input output functions

// start of the function PrintPopcornTime body having integer variable //bagOunces as parameter

void PrintPopcornTime(int bagOunces){

if (bagOunces < 3){ //if value of bagOunces is less than 3

 printf("Too small"); //displays Too small message in output

 printf("\n"); } //prints a new line

//the following else if part will execute when the above IF condition evaluates to //false and the value of bagOunces is greater than 10

else if (bagOunces > 10){

    printf("Too large"); //displays the message:  Too large in output

    printf("\n"); //prints a new line }

/*the following else  part will execute when the above If and else if conditions evaluate to false and the value of bagOunces is neither less than 3 nor greater than 10 */

else {

/* The following three commented statements can be used to store the value of bagOunces * 6 into result variable and then print statement to print the value of result. The other option is to use one print statement printf("%d",bagOunces * 6) instead */

    //int result;

    //result = bagOunces * 6;

    //printf("%d",result);

 printf("%d",bagOunces * 6);  /multiplies value of bagOunces  to 6

 printf(" seconds");

// seconds is followed with the value of bagOunces * 6

 printf("\n"); }} //prints a new line

int main(){ //start of main() function body

int userOunces; //declares integer variable userOunces

scanf("%d", &userOunces); //reads input value of userOunces

PrintPopcornTime(userOunces);

//calls PrintPopcornTime function passing the value in userOunces

return 0; }

Explanation:

<h2>Function 2:  </h2>

#include <stdio.h> //header file to use input output functions

// start of the function PrintShampooInstructions body having integer variable numCycles as parameter

void PrintShampooInstructions(int numCycles){

if(numCycles < 1){

//if conditions checks value of numCycles is less than 1 or not

printf("Too few."); //prints Too few in output if the above condition is true

printf("\n"); } //prints a new line

//else if part is executed when the if condition is false and else if  checks //value of numCycles is greater than 4 or not

else if(numCycles > 4){

//prints Too many in output if the above condition is true

printf("Too many.");

printf("\n"); } //prints a new line

//else part is executed when the if and else if conditions are false

else{

//prints "N: Lather and rinse." numCycles times, where N is the cycle //number, followed by Done

for(int N = 1; N <= numCycles; N++){

printf("%d",N);

printf(": Lather and rinse. \n");}

printf("Done.");

printf("\n");} }

int main() //start of the main() function body

{    int userCycles; //declares integer variable userCycles

   scanf("%d", &userCycles); //reads the input value into userCycles

   PrintShampooInstructions(userCycles);

//calls PrintShampooInstructions function passing the value in userCycles

   return 0;}

I will explain the for loop used in PrintShampooInstructions() function. The loop has a variableN  which is initialized to 1. The loop checks if the value of N is less than or equal to the value of numCycles. Lets say the value of numCycles = 2. So the condition evaluates to true as N<numCycles  which means 1<2. So the program control enters the body of loop. The loop body has following statements. printf("%d",N); prints the value of N followed by

printf(": Lather and rinse. \n"); which is followed by printf("Done.");

So at first iteration:

printf("%d",N); prints 1 as the value of N is 1

printf(": Lather and rinse. \n");  prints : Lather and rinse and prints a new line \n.

As a whole this line is printed on the screen:

1: Lather and rinse.

Then the value of N is incremented by 1. So N becomes 2 i.e. N = 2.

Now at second iteration:

The loop checks if the value of N is less than or equal to the value of numCycles. We know that the value of numCycles = 2. So the condition evaluates to true as N<numCycles  which means 2=2. So the program control enters the body of loop.

printf("Done."); prints Done after the above two lines.

printf("%d",N); prints 2 as the value of N is 2

printf(": Lather and rinse. \n");  prints : Lather and rinse and prints a new line \n.

As a whole this line is printed on the screen:

2: Lather and rinse.

Then the value of N is incremented by 1. So N becomes 2 i.e. N = 3.

The loop again checks if the value of N is less than or equal to the value of numCycles. We know that the value of numCycles = 2. So the condition evaluates to false as N<numCycles  which means 3>2. So the loop breaks.

Now the next statement is:

printf("Done."); which prints Done on the screen.

So as a whole the following output is displayed on the screen:

1: Lather and rinse.

2: Lather and rinse.

Done.

The programs along with their outputs are attached.

in Java programming Design a program that will ask the user to enter the number of regular working hours, the regular hourly pay
iren2701 [21]

Answer:

In Java:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

 int regularhour,overtimehour;

 float regularpay,overtimepay;

 Scanner input = new Scanner(System.in);

 

 System.out.print("Regular Hour: ");

 regularhour = input.nextInt();

 

 System.out.print("Overtime Hour: ");

 overtimehour = input.nextInt();

 

 System.out.print("Regular Pay: ");

 regularpay = input.nextFloat();

 

 System.out.print("Overtime Pay: ");

 overtimepay = input.nextFloat();

 

 float regulargross = regularhour * regularpay;

 float overtimegross = overtimehour * overtimepay;

 float totalgross = regulargross + overtimegross;

 

 System.out.println("Regular Gross Pay: "+regulargross);

 System.out.println("Overtime Gross Pay: "+overtimegross);

 System.out.println("Total Gross Pay: "+totalgross);

 

}

}

Explanation:

This line declares regularhour and overtimehour as integer

 int regularhour,overtimehour;

This line declares regularpay and overtimepay as float

 float regularpay,overtimepay;

 Scanner input = new Scanner(System.in);

 

This prompts the user for regular hour

 System.out.print("Regular Hour: ");

This gets the regular hour

 regularhour = input.nextInt();

 

This prompts the user for overtime hour

 System.out.print("Overtime Hour: ");

This gets the overtime hour

 overtimehour = input.nextInt();

 

This prompts the user for regular pay

 System.out.print("Regular Pay: ");

This gets the regular pay

 regularpay = input.nextFloat();

 

This prompts the user for overtime pay

 System.out.print("Overtime Pay: ");

This gets the overtime pay

 overtimepay = input.nextFloat();

 

This calculates the regular gross pay

 float regulargross = regularhour * regularpay;

This calculates the overtime gross pay

 float overtimegross = overtimehour * overtimepay;

This calculates the total gross pay

 float totalgross = regulargross + overtimegross;

 

This prints the regular gross pay

 System.out.println("Regular Gross Pay: "+regulargross);

This prints the overtime gross pay

 System.out.println("Overtime Gross Pay: "+overtimegross);

This prints the total gross pay

 System.out.println("Total Gross Pay: "+totalgross);
