VCC (Voltage Common Collector) is the higher voltage with respect to GND (ground). VCC is the power input of a device. It may be positive or negative with respect to GND. When the only positive power supply is used then VSS (Voltage Source Supply) means ground or zero. The Intel 8085 Microprocessor needs a power supply of +5 V DC for its working. Pin 40 of Intel 8085 is the Vcc pin. It should be connected to +5 V DC power supply. Pin 20 of 8085 is the Vss pin.
Use the charAt() method in Java to get a character located at a specified index.Let’s say the following is our string.String str = "Laptop...";Finding character at 3rd position.str.charAt(2);The following is the final example.Example Live Demopublic class Demo { public static void main(String[] args) { String str = "Laptop..."; System.out.println("String: "+str); System.out.println("Character at position 3 = " +str.charAt(2)); } }OutputString: Laptop... Character at position 3 = p
A Pascal’s triangle contains numbers in a triangular form where the edges of the triangle are the number 1 and a number inside the triangle is the sum of the 2 numbers directly above it.A program that demonstrates the creation of the Pascal’s triangle is given as follows.Example Live Demousing System; namespace PascalTriangleDemo { class Example { public static void Main() { int rows = 5, val = 1, blank, i, j; Console.WriteLine("Pascal's triangle"); for(i = 0; i
This example demonstrate about How to find edit text values start from Alphabet or Not.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code, we have taken edit text and button view to verify edit text data is starting with Alphabet.Step 3− Add the following code to java/MainActivity.xmlpackage com.example.myapplication; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.view.View; import android.widget.EditText; import android.widget.Toast; public class MainActivity extends AppCompatActivity { ...

An IP Address is an Internet Protocol address that is a series of numbers assigned to each device on a computer network. In C#, the class IPAddress class in the namespace System.Net deals with IP addresses.A program that is used to validate an IP address is given as follows −Example Live Demousing System; using System.Net; using System.Net.Sockets; using System.Text.RegularExpressions; namespace IPaddressDemo { class Example { public static void Main() { IPAddress IP; Console.WriteLine("Enter the IP Address: "); string ipAddr = Console.ReadLine(); ...

Usage of pointers in C# require the unsafe modifier. Also array elements can be accessed using pointers using the fixed keyword. This is because the array and the pointer data type are not the same. For example: The data type int[] is not the same as int*.A program that demonstrates accessing array elements using pointers is given as follows.Exampleusing System; namespace PointerDemo { class Example { public unsafe static void Main() { int[] array = {55, 23, 90, 76, 9, 57, 18, 89, 23, 5}; int n = ...
