B (each column gets a caption)
Answer:
import java.util.Scanner;
class Main {
public static void main (String args[])
{
Scanner input = new Scanner(System.in);
VendingMachine machine = new VendingMachine(20);
System.out.print("Enter nr to purchase: ");
int nrPurchased = input.nextInt();
System.out.print("Enter nr to re-stock: ");
int nrRestock = input.nextInt();
machine.Transaction(nrPurchased, nrRestock);
input.close();
}
}
class VendingMachine {
private int inventory;
public VendingMachine(int initialInventory) {
inventory = initialInventory;
}
public void Transaction(int nrToBuy, int nrToRestock) {
inventory += nrToRestock - nrToBuy;
System.out.printf("Inventory: %d bottles.\n", inventory);
}
}
Answer:
It leaves behind Error Code 5
Explanation:
This happens when the parameter provided fails the function requirement this could be as a result of wrong data type or when the parameter provided exceeds the function requirement.
Answer:
Either, "Ignore all" or "add '...' to dictionary"
Explanation:
If "Ignore all" is clicked, the software will ignore all the words which it believes is incorrect currently written. Whilst, adding it to the dictionary, the word will always be seen as spelt correctly on the application. Therefore, both get rid of the flagged word, but one is permanent.
Answer:
The program to this question can be given as:
Program:
#include <iostream> //header file
using namespace std; //using namespace.
void SwapValues(int* userVal1, int* userVal2); //function declaration.
void SwapValues(int* userVal1, int* userVal2) //function definition.
{ //function body.
//perform swapping
int t = *userVal1;
*userVal1 = *userVal2;
*userVal2 = t;
}
int main() //main method
{
int n1, n2; //define variable
cout<<"Enter first number :"; //message
cin>>n1; //input by user.
cout<<"Enter second number :"; //message
cin>>n2; //input by user.
SwapValues(&n1,&n2); //calling function.
cout<<"Swapped values"<<endl;
cout<<"first number is :"<<n1<<endl; //print value
cout<<"second number is:"<<n2<<endl; //print value
return 0;
}
Output:
Enter first number :3
Enter second number :8
Swapped values
first number is :8
second number is :3
Explanation:
The description of the above C++ language program can be given as:
- In the program, firstly we include the header file. Then we declare and define a function that is "SwapValues()" function in the function we pass two integer variable that is "userVal1 and userVal2" inside a function, we define an integer variable that is "t" and perform swapping.
- Then we define the main function in the main function we define two variables that is "n1 and n2" this variable is used to take value-form user. then we pass this value to function and print the function values.
