what statement about constructors is false? group of answer choices all constructors are passed a pointer argument constructors

Hunter-Best [27]

A return type cannot exist in the constructor. It ought to produce and deliver fresh objects. Consequently, a compilation error would result.

Including a return type in a constructor declaration is not allowed. A constructor has to accept one or more input parameters. In the absence of explicitly declared constructors for the class, Java will give a default constructor. The name of the constructor should match the class name. 2) The compiler will automatically produce a default parameterless constructor for a class if you don't define one. 3) All instance variables are initialized to default values, such as 0, null, and super(), by the default constructor.

Andrej [43]

Answer:

In C++:

#include <iostream>

using namespace std;

int main(){

int hour; char pkg; float bill = 0;

cout<<"Package: "; cin>>pkg;

cout<<"Hour: "; cin>>hour;

if(hour<=744 && hour >=0){

switch (pkg) {

case 'A':

bill = hour * 9.95;

if(hour >10){bill = 10 * 9.95 + (hour - 10) * 2;}

break;

case 'B':

bill = hour * 14.5;

if(hour >10){bill = 20 * 14.5 + (hour - 20) * 1;}

break;

case 'C':

bill = 19.95;

break;

default:

cout << "Package must be A, B or C";}

cout<<"Total Bills: $"<<bill; }

else{ cout<<"Hour must be 0 - 744"; }

return 0;

}

Explanation:

This declares all variables: int hour; char pkg; float bill=0;

This prompts the user for package type: cout<<"Package: "; cin>>pkg;

This prompts the user for number of hours: cout<<"Hour: "; cin>>hour;

This checks if hour is between 0 and 744 (inclusive)

if(hour<=744 && hour >=0){

If true, the following is executed

A switch statement to check valid input for package

switch (pkg) {

For 'A' package

case 'A':

Calculate the bill

bill = hour * 9.95;

if(hour >10){bill = 10 * 9.95 + (hour - 10) * 2;}

End of A package: break;

For 'B' package

case 'B':

Calculate the bill

bill = hour * 14.5;

if(hour >10){bill = 20 * 14.5 + (hour - 20) * 1;}

End of B package: break;

For C package

case 'C':

Calculate bill: bill = 19.95;

End of C package: break;

If package is not A, or B or C

default:

Prompt the user for valid package cout << "Package must be A, B or C";}

Print total bills: cout<<"Total Bills: $"<<bill; }

If hour is not 0 to 744: else{ cout<<"Hour must be 0 - 744"; }
