write the definition of a class clock. the class has no constructors and one instance variable of type int called hours.

A painting company has determined that for every 115 square feet or wall space, one gallon of paint and eight hours of labor wil

Kay [80]

The program to calculate the total paint cost and other values is given below.

#include <iostream>

using namespace std;

int main() {

int rooms, laborChrg = 18;

float paintChrg;

float feetPerRoom[rooms];

float paintReq, laborHrs, paintCost, laborCost, totalCost, totalsqft=0;

cout<<"Enter the number of rooms to be painted "<<endl;

cin>>rooms;

for(int i=0; i <= rooms; i++)

{

cout<<"Enter the square feet in room "<<endl;

cin>>feetPerRoom[i];

// shortcut operator which is equivalent to totalsqft = totalsqft + feetPerRoom[i];

totalsqft += feetPerRoom[i];

}

cout<<"Enter the cost of the paint per gallon "<<endl;

cin>>paintChrg;

laborHrs = (totalsqft/115)*8;

laborCost = laborHrs * laborChrg;

paintReq = totalsqft/115;

paintCost = paintReq * paintChrg;

totalCost = laborCost + paintCost;

cout<<"The number of gallons of paint required "<<paintReq<<endl;

cout<<"The hours of labor required "<<laborHrs<<endl;

cout<<"The cost of the paint is "<<paintCost<<endl;

cout<<"The labor charges are "<<laborHrs<<endl;

cout<<"The Total cost of the paint job is "<<totalCost<<endl;

return 0;

}

Explanation:

The header files for input and output are imported.

#include <iostream>

using namespace std;

All the variables are taken as float except labour charge per hour and number of rooms.

The user is asked to input the number of rooms to be painted. An array holds the square feet in each room to be painted.

cout<<"Enter the number of rooms to be painted "<<endl;

cin>>rooms;

for(int i=0; i <= rooms; i++)

{

cout<<"Enter the square feet in room "<<endl;

cin>>feetPerRoom[i];

totalsqft += feetPerRoom[i];

}

The above code asks for square feet in each room and calculates the total square feet to be painted simultaneously.

All the data to be displayed is calculated based on the values of labor charge per hour and gallons of paint needed, given in the question.

laborHrs = (totalsqft/115)*8;

laborCost = laborHrs * laborChrg;

paintReq = totalsqft/115;

paintCost = paintReq * paintChrg;

totalCost = laborCost + paintCost;

All the calculated values are displayed in the mentioned order.

Visual Basics: 1 ) Write an if/else statement that compares the double variable pH with 7.0 and makes the following assignments

Lemur [1.5K]

Answer:

visual basic: 1)

Module PHmodule

Sub Main()

'Creating a variable for each entity

dim ph as double = 0.0, neutral,base,acid as boolean

'Writing a line to show user what to do

console.writeline("Enter the pH :")

'Taking the value

ph=console.readline()

'using if & elseif statement for distingushing the values into correct catagories

if ph<7.0 then

neutral=false:base=false:acid=true

elseif ph>7.0 then

neutral=false:base=true:acid=false

elseif ph=7.0 then

neutral=true:base=false:acid=false

end if

'Printing the result

console.writeline(" Neutral :" & Neutral)

console.writeline(" base :" & base)

console.writeline(" acid :" & acid)

'command for staying in the command prompt for reading the result

console.readline()

End Sub

End Module

visual basic: 2)

Module AGEmodule()

Sub Main()

'Creating a variable for each entity

dim age,minors,adults,seniors as integer = 0

'Taking age from user

console.writeline("Enter the age")

age=console.readline()

'using if & elseif statement for checking the age differnce

if age<18 then'

minors +=1

else if age>18 and age<64 then

adults +=1

else if age>64 then

seniors +=1

end if

'printing result

console.writeline("minors="&minors)

console.writeline("adults="&adults)

console.writeline("seniors="&seniors)

'command for reading the result

console.readline()

End Sub

End Module

Explanation:

visual basic 1) it is very simple program which allow us to find if the substance is acidic, basic or neutral. we use sim statement for making a variable as double (gives value in decimal) which allow to take a value from the user through console.readline() command and then by using the if statement we apply the condition if the ph is less then, greator then or equal to 7.0 value. thus the program gives us the answer. console.writeline() command is used to print a command on the screen while console.readline() command let us read the lines until we press enter.

visual basic 2)a program which allow us to count and add number of persons according to their age. we use dim statement for creating the variable as integers in which we take the age from user and then after checking it through if statement we increment according to three categories i.e. minors, adults, seniors. the console.writeline() command allow us to print anything on screen and console.readline() allowus to take value while compiling.

thank you...

This operator represents the logical AND.

sdas [7]

Answer:

C. &&

Explanation:

Of the options provided:

A) ++ : increment operator. For example : ++1 = 2

B) || : Logical OR operator. A || B is true if any one of A or B is true.

C) && : Logical AND operator. A && B is true if both A and B are true.

A B A && B

False False False

False True False

True False False

True True True

D) @ : Ampersand character (commonly used in email addresses) e.g, [email protected]

A pointing device uses light to determine hand motion.

kirill [66]

The answer to this is Optical mouse.

The reason the answer is optical mouse is because the optical mouse is a computer mouse which uses a light source, typically a light-emitting diode, and a light detector, such as an array of photodiodes, to detect movement relative to a surface.

Hope this helped :)
have a great day
