Answer:
The program in Python is as follows:
qty = int(input("Quantity: "))
price = 100 * qty
if qty >1000:
price = (100 - 0.10 * 100) * qty
print("Cost: "+str(price))
Explanation:
This prompts the user for the quantity
qty = int(input("Quantity: "))
This calculates the price or cost, without discount
price = 100 * qty
This checks if the quantity is greater than 1000
if qty >1000:
If yes, this calculates the price or cost, after discount
price = (100 - 0.10 * 100) * qty
This prints the calculated cost
print("Cost: "+str(price))
Answer:
import java.util.*;
public class MyClass {
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
System.out.print("Input a word: ");
String userinput = input.nextLine();
for(int i =0;i<userinput.length();i+=2) {
System.out.print(userinput.charAt(i));
}
}
}
Explanation:
This line prompts user for input
System.out.print("Input a word: ");
This declares a string variable named userinput and also gets input from the user
String userinput = input.nextLine();
The following iterates through every other character of userinput from the first using iteration variable i and i is incremented by 2
for(int i =0;i<userinput.length();i+=2) {
This prints characters at i-th position
System.out.print(userinput.charAt(i));
The correct answer isn’t really a choice shown. I would choose D because if a work doesn’t have a copyright symbol that doesn’t mean it’s in the public domain. In a real life situation it would be best to ask the creator before you use their work. If they say it’s in the public domain then you’re fine, but even if they say you can use it that doesn’t mean it’s in the public domain, it just means that you have permission to use it.
