Aim:
To perform the simple calculator using c sharp.net application.Algorithms:
Step1: Create a new folder in a “d” drive and open the new text document in the folder.Step2: Type the program in the new notepad file and save the file “simcalc”
Step3: Use the switch case to determine various operations in the program.
Step4: The operators are mainly used to perform the operations, Addition,subtraction, +multiplication and division.
Step5: Save the program with the extension of .cs
Step6: Open the visual studio comment prompt to compile and run the program.
Step7: Compile the program & given the program name .cs
Step8: Run the program by giving the program name and stop the program.
Program:
using System;
class simcalc
{
public static void Main(string[] args)
{
double a,b,rpt=1;
int choice;
while(rpt!=0)
{
Console.WriteLine("select the operations:");
Console.WriteLine("1.addition");
Console.WriteLine("2.subtraction");
Console.WriteLine("3.multiplication");
Console.WriteLine("4.division");
Console.WriteLine("5.exit");
Console.WriteLine("Enter your choice:");
choice=int.Parse(Console.ReadLine());
switch(choice)
{
case 1:
Console.WriteLine("Enter two number:");
a=double.Parse(Console.ReadLine());
b=double.Parse(Console.ReadLine());
Console.WriteLine("Result of addition:"+(a+b));
break;
case 2:
Console.WriteLine("Enter two number:");
a=double.Parse(Console.ReadLine());
b=double.Parse(Console.ReadLine());
Console.WriteLine("Result of subtraction:"+(a-b));
break;
case 3:
Console.WriteLine("Enter two number:");
a=double.Parse(Console.ReadLine());
b=double.Parse(Console.ReadLine());
Console.WriteLine("Result of multiplication:"+(a*b));
break;
case 4:
Console.WriteLine("Enter two number:");
a=double.Parse(Console.ReadLine());
b=double.Parse(Console.ReadLine());
if(b==0)
{
Console.WriteLine("division not possible");
}
else
{
Console.WriteLine("resultof division:"+(a/b));
}
break;
case 5:
rpt=0;
break;
default:
Console.WriteLine("invalid selection");
break;
}
}
}
}
OUTPUT:
BY
REGU RAM SV.
super dude keep going........,
