WAP to swap two numbers

 using System;

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace swap
{
Class Program
{
static void main(string[] args)
{
int A, B, C;
Console.WriteLine("Input first number.");
A= Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Input second number.");
B= Convert.ToInt32(Console.ReadLine());
Console.WriteLine("The number before swapping are : A={0} B= {1}", A,B)
C= A;
A= B;
B = C;
Console.WriteLine("The number after swapping are: A={0}  B = {1}", A,B);
Console.ReadLine();
}
}
}

OUTPUT:
Input first number. 5
Input second number. 6
The number before swapping are : A = 5  B = 6
The number after swapping are : A= 6      B= 5

Physical variables and transducer

unit 3 Physical Variables and transducers  Sensor Sensors are electrical devices that have the capability of sensing different physical variables. The sensor may be classified on different bases one of them is a physical quantity. Hence on the basis of a physical quantity or physical vibration involved the sensors are classified as: Resistive sensor  The input being measured is transformed into a change in resistance. examples: potentiometer, resistance thermometer, strain gauge, etc. Inductive sensor The input being measured is transformed into a change in resistance. example LVDT. Capacitive Sensor The input being measured is transformed into a change in capacitance. example: capacitive Displacement sensor. On the basis of power supply required: Active Sensor Active sensors are those which do not require an external power supply.  example: thermo-couple Passive Sensor Passive Sensors are those which require a power supply. example: Potentiometer. Physical variables and ...
