## Q. C# Program to Print Fibonacci Series upto N terms.

Here you will find an algorithm and program in C# programming language to print fibonacci series. First let us understand what fibonacci series means.

Explanation : The Fibonacci sequence is a sequence consisting of a series of numbers and each number is the sum of the previous two numbers. For Example :- 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, …….

## Fibonacci Series Algorithm

```START
Step 1->Declare variables i, a, b, nextTerm
Step 2->Initialize the variables, a=0, b=1, and nextTerm = 0
Step 3->Enter the number of terms of Fibonacci series to be printed
Step 4->Repeat below steps n times
-> print the value of a
-> nextTerm = a + b
-> a = b
-> b = nextTerm
-> increase value of i each time by 1
STOP

```

# C# Program to Print Fibonacci Series

```using System;
public class Demo{
public static void Main(string[] args){
int a = 0, b = 1, nextTerm, i, n = 9;
for(i=0 ;i < n; ++i){
Console.Write(a+" ");
nextTerm = a + b;
a = b;
b = nextTerm;
}
}
}
```

#### Output

```0 1 1 2 3 5 8 13 21
```
