Answer:
The code will give an error that is "At least one public class is required in main file".
Explanation:
In the given code if we do not use the public access modifier to the class. It will give an error so, the correct code to this question as follows:
Program:
import java.util.HashSet; //import package
public class A //define class as public.
{
public static void main(String[ ] args) //define main method.
{
HashSet set = new HashSet(); //creating hashset object.
set.add("A"); //add alphabet in hashset
set.add("B"); //add alphabet in hashset
set.add("C"); //add alphabet in hashset
System.out.print("Size of HashSet is :"set.size()); //print the size of hashset.
}
}
Output:
Size of HashSet is : 3
Explanation of the program:
- In the above program, we define a public class that is "A" and inside the class, we define the main method.
- Inside the main method, we create a HashSet class object that is "set".
- To add elements in HashSet we use add() function that adds elements and in the last, we use the size() function that prints the size HashSet.
With the aid of pointer-based arithmetic operations and the usage of pointers in comparison operations, address arithmetic is a technique for determining the address of an object. Pointer arithmetic is another name for address arithmetic.
The pointers can be used for mathematical operations like addition, subtraction, etc. The outcome of an arithmetic operation on the pointer, however, will likewise be a pointer if the other operand is of type integer because we know that the pointer includes the address. These operations are addition and subtraction. In C++, a pointer's value can be increased or decreased. It signifies that we can change the pointer's value by adding or removing integer values. A pointer arithmetic can be subtracted (or added) from another in a manner similar to this.

#SPJ4
Answer:
The answer is "1918".
Explanation:
The RFC stands for "remote function call", it is also known as an abbreviated form. It is an application, that responses in a technical online design Task Force, it is also known as a document, which was prepared for review by shareholders to collects some information.
The RFC reverses is also known as an idea, that uses IP version 4 to reverse the IP address, this process is done by TCP/IP protocol, which is defined under RFC 1918.
No, not really cuz I think that would be too personal for the president.
Answer:
#include <iostream>
using namespace std;
void PrintPopcornTime (int bagOunces){
if (bagOunces < 2){
cout << "Too small"<<endl;
}
else if (bagOunces > 10){
cout << "Too large"<<endl;
}
else{
cout << bagOunces*6 <<" seconds"<<endl;
}
}
int main(){
PrintPopcornTime(7);
return 0;
}
Explanation:
Create a function called PrintPopcornTime that takes one parameter, bagOunces
Check the bagOunces using if-else structure. If it is smaller than 2, print "Too small". If it is greater than 10, print "Too large". Otherwise, calculate and print 6*bagOunces followed by " seconds".
Call the function in the main function with parameter 7. Since 7 is not smaller than 2 or not greater than 10, "42 seconds" will be printed.
