Write a program to generate Fibonacci series using For loop C++ Language

In this article i will  write a program to generate Fibonacci series/sequence up to the given limit using in C++ language using For loop.

Fibonacci series: In Fibonacci series, first number is 0 and second number is 1 and further next number is the sum/addition of previous two numbers.

 0 1 1 2 3 5 8 13 21 34 55....... this is the example of Fibonacci series.

Explanation:

First Number = 0

Second Number = 1

Third Number = 0 + 1 =1

Fourth Number = 1 + 1 =2

Fifth Number = 2 + 1 =3

Sixth Number =3 + 2 = 5

Seventh Number = 5 + 3 =8 and so on...

 Let's create program to generate Fibonacci Series with For loop using  C++language.

#include<conio.h>

#include<iostream.h>

int main()

{

 int i,n,first=0,second=1,fibo;

 clrscr();

 cout<<"Enter the number of terms: ";

 cin>>n;

 cout<<"\nFibonacci series:\n";

 cout<<first<<"\t"<<second;

 for(i=0;i<n-2;i++)

 {

  fibo=first+second;

  first=second;

  second=fibo;

  cout<<"\t"<<fibo;

 }

 getch();

 return 0;

}

Run the program using Ctrl+F9

Output:

Enter the number of terms: 10

Fibonacci Series
