Answer:
2
Explanation:
The mathematical answer would be 2. To get 11, one would simply put the 1's next to each other but there is an addition symbol. 32 is an irrational number to think of for an answer because there are no other numbers to add or multiply with the 1's to achieve 32. 9 is also irrational for the same reason.
A complete program with the method ShowCar:
import java.util.Scanner; // header file
public class ShowChar
{
public static void main(String[] args)
{
String lnOfText;
int i;
Scanner input = new Scanner(System.in);
System.out.print("Enter a line of text:");
lnOfText = input.nextLine();
System.out.print(" Enter your index: ");
i = input.nextInt();
show_Char(lnOfText,i);
}
public static void show_Char(String str_a, int i)
{
System.out.print(str_a.charAt(i));
}
}
In this program, both the inputs ie. a sentence or line of text as well as the index position is obtained. A method is written to find the string at that particular position. Finally the method prints that character at the particular index.
