A function is executed when it is
Alekssandra [29.7K]

Answer:

D. called

Explanation:

A function is executed when it is called.

Function definition comprises of the code body of the function.For example:

int add(int a, int b){

    return a+b;

}

Function declaration or function prototype specifies the signature of the function ( number and type of arguments, return type). e.g,

int add(int a,int b);

Function call is when the function is executed with actual arguments:

add(2,4);

This will return 6 upon execution of function body.

(Palindrome integer) Write the methods with the following headers // Return the reversal of an integer, i.e., reverse(456) retur
Debora [2.8K]

Answer:

import java.util.Scanner;

public class PalindromeInteger {

public static void main(String[] args) {

 // Create an object of the Scanner class to allow for user's inputs

 Scanner input = new Scanner(System.in);

 // Create a prompt to display the aim of the program.

 System.out.println("Program to check whether or not a number is a palindrome");

 // Prompt the user to enter an integer number.

 System.out.println("Please enter an integer : ");

 // Receive user's input and store in an int variable, number.

 int number = input.nextInt();

 // Then, call the isPalindrome() method to check if or not the

 // number is a  palindrome integer.

 // Display the necessary output.

 if (isPalindrome(number)) {

  System.out.println(number + " is a palindrome integer");

 }

 else {

  System.out.println(number + " is a not a palindrome integer");

 }

}

// Method to return the reversal of an integer.

// It receives the integer as a parameter.

public static int reverse(int num) {

 // First convert the number into a string as follows:

 // Concatenate it with an empty quote.

 // Store the result in a String variable, str.

 String str = "" + num;

 // Create and initialize a String variable to hold the reversal of the  

 // string str. i.e rev_str

 String rev_str = "";

 // Create a loop to cycle through each character in the string str,

 // beginning at  the last character down to the first character.

 // At every cycle, append the character to the rev_str variable.

 // At the end of the loop, rev_str will contain the reversed of str

 for (int i = str.length() - 1; i >= 0; i--) {

  rev_str += str.charAt(i);

 }

 // Convert the rev_str to an integer using the Integer.parseInt()

 // method.  Store the result in an integer variable reversed_num.

 int reversed_num = Integer.parseInt(rev_str);

 // Return the reversed_num

 return reversed_num;

}

// Method to check whether or not a number is a palindrome integer.

// It takes in the number as parameter and returns a true or false.

// A number is a palindrome integer if reversing the number does not

//  change the  number itself.

public static boolean isPalindrome(int number) {

 // check if the number is the same as its reversal by calling the

 //reverse()  method declared earlier. Return true if yes, otherwise,

               // return false.

 if (number == reverse(number)) {

  return true;

 }

 return false;

}

}
