How the logic works?

Question

public static void Main()
{
int n;
int a = 0;
int b = 1;

Console.Write("Enter the limit : ");
n = int.Parse(Console.ReadLine());

for (int i = 0; i < n; i++)
{
Console.WriteLine(a);
int temp = a;
a = b;
b = temp + b;
}

Console.Read();

Answer 1

n - no. of values to print.
temp - temporary variable for the purpose of swapping a and b.

In fibonacci series the next umber is determined by adding the number at current position and previous position.

Here, we print a number and swap it to a temporary variable then get the next number from b to a, then we get the next to next number on b by adding the current and last number.
