Program to convert KiloBytes to Bytes and Bits in C++
Given with the input as KiloBytes and the task is to convert the given input into number of bytes and bits.Bit − In computers, bit is the smallest unit represented with two integer value 0 and 1 and all the information in computer is processed as a sequence of these two digits.N-bits = 2 ^ N patterns, where N can be any integer value starting from 1.Byte − In computers, byte is represented with 8 bits. Byte is capable of holding one character to numbers ranging between 0 and 255.1 byte = 8 bitsWhich means 2 ^ 8 patterns which ...
Read MoreChecked Vs unchecked exceptions in Java programming.
Checked exceptionsA checked exception is an exception that occurs at the compile time, these are also called as compile-time exceptions. These exceptions cannot simply be ignored at the time of compilation; the programmer should take care of (handle) these exceptions.When a checked/compile time exception occurs you can resume the program by handling it using try-catch blocks. Using these you can display your own message or display the exception message after the execution of the complete program.Exampleimport java.io.File; import java.io.FileInputStream; public class Test { public static void main(String args[]){ System.out.println("Hello"); try{ ...
Read MoreProgram to convert IP address to hexadecimal in C++
Given with the input as an IP address value and the task is to represent the given IP address as its hexadecimal equivalent.What is IP addressIP address or Internet protocol is a unique number to that uniquely describes your hardware connected to a network. Internet means over the network and protocol defines the set of rules and regulations that must be followed for connection. Because of IP address only it is possible for a system to communicate with another system over a network. There are two versions of IP that are −IPv4(Internet Protocol Version 4)IPv6(Internet Protocol Version 6)IP address is ...
Read MoreShadowing of static methods in Java
When superclass and the subclass contain the same instance methods including parameters, when called, the superclass method is overridden by the method of the subclass.Exampleclass Super{ public void sample(){ System.out.println("Method of the Super class"); } } public class MethodOverriding extends Super { public void sample(){ System.out.println("Method of the Sub class"); } public static void main(String args[]){ MethodOverriding obj = new MethodOverriding(); obj.sample(); } }OutputMethod of the Sub classMethod shadowingWhen superclass and subclass contain the same method including parameters and if they are ...
Read MoreDifference between a Static Queue and a Singly Linked List in Java.
In Java List and Queue both are introduced as an ordered list of objects, where the same object may be added more than once. The difference between both comes in the manner of adding elements. In the queue, all the elements get inserted at the rear and removed from the front while we can add an element anywhere in the list.Sr. No.KeyStatic QueueSingly Linked List1Data initialization.Static Queue works in first out(FIFO) fashion as all the elements get inserted at the REAR and removed from the FRONT of the queue.In the case of Singly Linked List, one can add elements anywhere ...
Read MoreCheck if a number can be expressed as 2^x + 2^y in C++
Here we will see, if we can represent a number as sum of two non-zero powers of 2. So we will check the given number N can be represented as (2x + 2y) where x, y > 0. Suppose a number is 10, this can be represented as 23 + 21.The approach is simple. There are two cases. If the number n is even, it can be represented as 2x. Where x > 0. Another case is that is N is odd, it can never be represented as sum of powers of 2. We cannot use power as 0, so ...
Read MoreProgram to calculate area and perimeter of equilateral triangle in C++
What is Equilateral Triangle?As the name suggests, equilateral triangle is the one that have equal sides and also it have equal interior angles of 60° each. It is also known as regular triangle because it’s a regularpolygonProperties of equilateral triangle are −3 sides of equal lengthInterior angles of same degree which is 60Given below is the figure of equilateral triangleProblemGiven with the side of equilateral triangle the task is to find the area and perimeter of a triangle where area is the space occupied by the shape and perimeter is the space occupied by its boundaries.To calculate area and perimeter ...
Read MoreNew ways to Assign values to Variables in C++ 17 ?
In C++ 17, there are introduced two new ways by which a programmer can assign values to a variable or declared them. In this update, elser then the classical way of assigning values to a variable the following two ways to initialise values.Classical methodInitially the assignment operator ‘=’ is used for assignment and declaration of a variable. assignment of a variable using = looks like, datatype variable_name = value;Example, int val = 243;New methodUniform initialisationIn uniform initialisation of variables we do not use the ‘=’ operator. the value is enclosed inside a pair of curly braces ' {} '. Value ...
Read MoreCan we assign values to final arrays in Java?
The array is a container that can hold a fixed number of items and these items should be of the same type. Most of the data structures make use of arrays to implement their algorithms. The following are the important terms to understand the concept of Array.Element − Each item stored in an array is called an element.Index − Each location of an element in an array has a numerical index, which is used to identify the element.The size of the array will be determined at the time of creation.Examplepublic class ArrayExample { public static void main(String args[]){ ...

Here we will check whether we can represent a number like ab or not. Suppose a number 125 is present. This can be represented as 53. Another number 91 cannot be represented as power of some integer value.AlgorithmisRepresentPower(num): Begin if num = 1, then return true for i := 2, i2
