Fibonacci series:The first two Fibonacci numbers are 0 and 1, and each remaining number is the sum of the previous two

e.g.: 0 1 1 2 3 5 8 13 21 ....

A number n is taken from user and the series is displayed upto nth term.

Select To use this code as it is.. select and copy paste this code into code.cpp file :)

- #include<iostream.h>
- #include<conio.h>
- void main()
- {
- clrscr();
- int a=0,b=1,c=0,n;
- cout<<"Enter the number of terms you wanna see: ";
- cin>>n;
- cout<<a<<" "<<b<<" ";
- for(int i=1;i<=n-2;i++)
- {
- c=a+b;
- a=b;
- b=c;
- //Coding by: Snehil Khanor

- cout<<c<<" ";
- }
- getch();

in FOR statement "i<=n" will come :)

if i<=n is taken then the no of terms displayed is 17...!

#define fibonacci

#include

void main()

{

int a,b,c;

for(a=0,b=1,c=0;c<10;c=a+b,a=b,b=c)

cout<<c;

}

AM I CORRECT? BUT ITS NOT FOR N TERMS.. O/P S BASED ON VALUE OF C... PLS REPLY FOR ANY CORRECTION

can u specify #fibonacci jus like dat?? sorry if this is silly

instead of for(int i=1;i<=n-2;i++)

use for(int i=0;i<=n-2;i++)

its show perfect series

it shows correct answers.. thanks

the programs on this site are so useful for computer science students..........

C program to convert given number of days into years,weeks and days#include

cout<<”enter number of terms (n)=”;

cin>>n;

cout<<a<<setw(4)<<b;

while (count<=n)

c=a+b;

cout<<setw(4)<<c;

a=b;

b=c;

count++;

}

getch();

return 0;

}

can u plz post a program of fibonacci series using a another function

void fib(int n)

#include

#include

void main()

{

clrscr();

{

int n,a=0,b=1,c,i;

cout<<"enter the value of n";

cin>>n;

cout<<"fibonacci series is=";

for(i=0;i<n;i++)

{

if(i<=1)

{

c=i;

}

else

c=a+b;

a=b;

b=c;

}

cout<<c<<",";

}

getch();

}

u r already printing the first two numbers

See this one.. little more advanced..

actually whoever the programmer is doesn't know anything related to programming... i am atleast a 100 times better programmer....

#include

#include

void main()

{

int n,i,a=0,b=1,series;

cout<<"enter fibonnaci series";

for(i=0;i<n;i++)

{

if(i<=1)

series=i;

else

{

series=a+b;

a=b;

b=series;

}

cout<<series<<endl;

}

}

C++ Program to Generate Fibonacci series

Fibonacci Series is in the form of 0, 1, 1, 2, 3, 5, 8, 13, 21,...... To find this series we add two previous terms/digits and get next term/number.

int a=-1,b=1,i,c,n;

cout<"enter limit:";

cin>>n;

for(i=0;i<n;i++)

{

c=a+b;

cout<<c<<"\n";

a=b;

b=c;

}

Very informative article.Thank you author for posting this kind of article .

Both are really good,

Cheers,
