Hey,
static void Main(string[] args)
{
int lim_low,lim_up;
int a = 0;
int b = 1;
int c;
Console.WriteLine("Enter first Value");
lim_low = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Enter Last Value");
lim_up = Convert.ToInt32(Console.ReadLine());
while (a
{
if (a > lim_low)
Console.WriteLine(a);
c = a + b;
a = b;
b = c;
}
Console.ReadLine();
}

Hi Yalavarthi,

Please see the below code.
class Program
{

static void Main(string[] args)
{
Program p = new Program();
int lower=Convert.ToInt16(Console.ReadLine());
int upper = Convert.ToInt16(Console.ReadLine());
Fibonacci( lower, upper);
Console.ReadKey();
}
public static void Fibonacci(int lower,int upper)
{
int a = 0;
int b = 1;

while(b
{
int temp = a;
a = b;
b = temp + b;
if(a>lower)
Console.WriteLine(a);
}

}
}
If the above solution is helpful then,accept the answer.

using System;
namespace Fibonaccinumber
{
class Program
{
static void Main(string[] args)
{

int a=0; // assigning initaial value for first varible
int b=1; // assigning initaial value for second varible
int c=1; // assigning initaial value for third varible
Console.WriteLine(a);
Console.WriteLine(b);
while (true)
{
c = a + b;
if (c >= 200)
{
break;
}
Console.WriteLine(c);
a = b;
b = c;
}
Console.Read(); // to keep windows screen after running
}
}
}
