A method may take zero or more parameters as input. To demonstrate this, we look at the asserts we use on HackerRank. Sometimes, we have to check whether a given number a is within the range b and c (where b c, and both…
Each object in Ruby may have methods associated with it. To demonstrate this, we want you to print whether a number is even or odd. A number has an even? method associated with it, which returns true or false based on…
Everything is an object in Ruby. For instance, if you type print self in the code-editor, Ruby treats self as the object in which it is currently referred to. Give it a try! Solution in ruby
Objective In this challenge, you will learn to implement the basic functionalities of pointers in C. A pointer in C is a way to share a memory address among different contexts (primarily functions). They are primarily…
Objective In this challenge, you will learn simple usage of functions in C. Functions are a bunch of statements glued together. A function is provided with zero or more arguments, and it executes the statements on it…
Objective The fundamental data types in c are int, float and char. Today, we're discussing int and float data types. The printf() function prints the given statement to the console. The syntax is printf("format…
Consider an -element array, , where each index in the array contains a reference to an array of integers (where the value of varies from array to array). See the Explanation section below for a diagram. Given , you must…
An array is a series of elements of the same type placed in contiguous memory locations that can be individually referenced by adding an index to a unique identifier. Declaration: Accessing elements of an array: You'll…
A pointer in C is a way to share a memory address among different contexts (primarily functions). They are primarily used whenever a function needs to modify the content of a variable, of which it doesn't have…
Functions are a bunch of statements glued together. A function is provided with zero or more arguments, and it executes the statements on it. Based on the return type, it either returns nothing (void) or something. A…
A for loop is a programming language statement which allows code to be repeatedly executed. The syntax for this is expression_1 is used for intializing variables which are generally used for controlling terminating flag…
if and else are two of the most frequently used conditionals in C/C++, and they enable you to execute zero or one conditional statement among many such dependent conditional statements. We use them in the following…
Some C++ data types, their format specifiers, and their most common bit widths are as follows: Int ("%d"): 32 Bit integer Long ("%ld"): 64 bit integer Char ("%c"): Character type Float ("%f"): 32 bit real value Double…
Objective In this challenge, we're practicing reading input from stdin and printing output to stdout. In C++, you can read a single whitespace-separated token of input using cin, and print output to stdout using cout…
The Calendar class is an abstract class that provides methods for converting between a specific instant in time and a set of calendar fields such as YEAR, MONTH, DAY_OF_MONTH, HOUR, and so on, and for manipulating the…
You are given an integer , you have to convert it into a string. Please complete the partially completed code in the editor. If your code successfully converts into a string the code will print "Good job". Otherwise it…
"In computing, End Of File (commonly abbreviated EOF) is a condition in a computer operating system where no more data can be read from a data source." — (Wikipedia: End-of-file) The challenge here is to read lines of…
Java has 8 primitive data types; char, boolean, byte, short, int, long, float, and double. For this exercise, we'll work with the primitives used to hold integer values (byte, short, int, and long): A byte is an 8-bit…
We use the integers , , and to create the following series: You are given queries in the form of , , and . For each query, print the series corresponding to the given , , and values as a single line of space-separated…
Objective In this challenge, we're going to use loops to help us do some simple math. Task Given an integer, , print its first multiples. Each multiple (where ) should be printed on a new line in the form: N x i =…
