TaskTo complete this challenge, you must save a line of input from stdin to a variable, print Hello, World. on a single line, and finally print the value of your variable on a second line.You've got this!Note: The instructions are Java-based, but we support submissions in many popular languages. You can switch languages using the drop-down menu above your editor, and the variable may be written differently depending on the best-practice conventions of your submission language.Input FormatA single line of text denoting (the variable whose contents must be printed).Output FormatPrint Hello, World. on the first line, and the contents of on the second line.Sample InputWelcome to 30 Days of Code!Sample OutputHello, World. Welcome to 30 Days of Code!ExplanationOn the first line, we print the string literal Hello, World.. On the second line, we print the contents of the variable which, for this sample case, happens to be Welcome to 30 Days of Code!. If you do not print the variable's contents to stdout, you will not pass the hidden test case.

This challenge requires you to print on a single line, and then print the already provided input string to stdout. If you are not familiar with C, you may want to read about the printf() command.ExampleThe required output is:Hello, World! Life is beautiful

Complete the main method in the HelloWorld class to Declare a String object s, assigned with the literal String "Hello World!"Print the String object s as formatted outputDeclare the integer-typed variable len, and use the .length() String method on s to assign it's valuePrint the variable len as formatted outputDeclare the char-typed variable ch and use the .charAt(6) String method on s to assign it's valuePrint the variable ch as formatted outut

n this challenge, we will learn some basic concepts of C that will get you started with the language. You will need to use the same syntax to read input and write output in many C challenges. As you work through these problems, review the code stubs to learn about reading from stdin and writing to stdout.TaskThis challenge requires you to print on a single line, and then print the already provided input string to stdout. If you are not familiar with C, you may want to read about the printf() command.ExampleThe required output is:Hello, World! Life is beautiful Function DescriptioComplete the main() function below.The main() function has the following input:string s: a stringPrints*two strings: * "Hello, World!" on one line and the input string on the next line.Input FormatThere is one line of text, .Sample Input 0Welcome to C programming.Sample Output 0Hello, World!Welcome to C programming.

In this challenge, you must read an integer, a double, and a String from stdin, then print the values according to the instructions in the Output Format section below. To make the problem a little easier, a portion of the code is provided for you in the editor.Note: We recommend completing Java Stdin and Stdout I before attempting this challenge.Input FormatThere are three lines of input:The first line contains an integer.The second line contains a double.The third line contains a String.Output FormatThere are three lines of output:On the first line, print String: followed by the unaltered String read from stdin.On the second line, print Double: followed by the unaltered double read from stdin.On the third line, print Int: followed by the unaltered integer read from stdin.To make the problem easier, a portion of the code is already provided in the editor.Note: If you use the nextLine() method immediately following the nextInt() method, recall that nextInt() reads integer tokens; because of this, the last newline character for that line of integer input is still queued in the input buffer and the next nextLine() will be reading the remainder of the integer line (which is empty).Sample Input423.1415Welcome to HackerRank's Java tutorials!Sample OutputString: Welcome to HackerRank's Java tutorials!Double: 3.1415Int: 42

Write a program that carries out the following tasks:Open a file with the name hello.txt.Store the message “Hello, World!” in the file.Close the file.Open the same file again.Read the message into a string variable and print it.
