Question

Given a string on one line and an integer index on a second line, output the character of the string at that index.

Answer 1

The code is in Java.

It uses a built-in function named chartAt() to get the character at the entered index.

Recall that built-in functions are functions that are already defined in the language. We can use them by calling the function and passing the required argument. The chartAt() function takes an index and returns the character at that index.

Comments are used to explain each line of the code.

//Main.java

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

    //Scanner object to get input from the user

    Scanner input = new Scanner(System.in);

   

    //Declaring the variables

    String s;

    int index;

    char c;

   

    //Getting the inputs

    s = input.nextLine();

    index = input.nextInt();

   

    //Getting the character at the index using the charAt() function

    c = s.charAt(index);

   

    //Printing the character

 System.out.println(c);

}

}
