How to get the length of Bob?
Explanation:
Answer:
If a method does not return a value, the return-value-type in the method declaration can be omitted.
Explanation:
If a method does not return a value, the return-value-type in the method declaration can be omitted is a false statement.
Answer:
the recycle bin?
Explanation:
usually when you overwrite something or delete it, it doesn't get entirely deleted rather stored in the recycle bin on your desktop i believe, and so you could retrieve applications through there
Answer:
The code is given below. Follow the question and the code definitions for better understanding.
Explanation:
#include<iostream>
#include<string>
using namespace std;
int main(){
string pastWord="";
string currentWord,nextWord;
int n,t;
int singleton=0;
int consecutive=0;
cout<<"Enter words. ('xxxxx' to exit):\n";
cin>>nextWord;
do{
currentWord=nextWord;
cin>>nextWord;
if ( (currentWord!=pastWord)&&(currentWord!=nextWord) )
singleton++;
else if((currentWord==pastWord)&&(currentWord!=nextWord))
consecutive++;
pastWord=currentWord;
}while(nextWord!="xxxxx");
n=singleton;
t=consecutive;
cout<<"There were "<<n<<" singletons and "<<t<<" consecutive repetitions.";
cin.get();
return 0;
}
Answer:
- import java.util.Scanner;
- public class MealPriceCalculation{
-
- public static void main(String[] args) {
-
- Scanner input = new Scanner(System.in);
- System.out.print("Enter meal price: ");
- double meal = input.nextDouble();
- System.out.print("Enter tip: ");
- double tip = input.nextDouble();
-
- calculatePrice(meal,tip);
- calculatePrice(meal,(int)tip);
-
- }
-
- public static void calculatePrice(double meal, double tip){
- System.out.println("Total meal price: $" + (meal + tip) );
- }
-
- public static void calculatePrice(double meal, int tip){
- System.out.println("Total meal price $" + (meal+tip));
- }
- }
Explanation:
The solution code is written in Java.
Overload methods are the methods that share the same name but with different method signature. In this question, we create two overload methods calculatePrice (Line 17-23). One version will accept parameter meal and tip in double type and another will accept parameter meal in double but tip in integer. Both of this method are doing the same job which is just printing the total of meal.
In the main program, create a Scanner object and use it to prompt user to input meal price and tip (Line 6-10). Next call the calculatePrice method for twice. In the first time, pass meal and tip as double type data to calculatePrice method (Line 12). In the second time, pass meal in double but tip in integer to the method. Only the method with parameter list that match the argument data type will be implemented and output the total meal price.
