What is Fibonacci Series?
The first two Fibonacci numbers are 0 and 1 then next number is addition of previous two numbers.
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89.....
In mathematics it is defined by recurrence relation.
Program Code
//C Program for generate Fibonacci series
#include "stdio.h"
#include "conio.h"
void main()
{
int a,b,c,i,n;
clrscr();
a=0;
b=1;
printf("\n enter n for how many times generate series");
scanf("%d",&n);
printf("\n FIBONACCI SERIES\n");
printf("\t%d\t%d",a,b);
for(i=0;i<n;i++)
{
c=a+b;
a=b;
b=c;
printf("\t%d",c);
}
getch();
}

thanks.......
thanks
can u write this program without taking 0,1 as initial values for a and b variables
wrong!!!!!
u hav printed 8 no's bt v ned only 6 no's???
if you take
a=-1
b=1
means u don't need to print a,b
wow thanks its totally right :)
mind blowing its right
thanku
dis is wrong dude ;
when u want 3rd number in the series (dat is 1) you hav to give value of n == 1...
I hope this solves your problem
#include
#include
void main()
{
int a,b,c,i,n;
a=0;
b=1;
printf("Enter number of terms of the series to be generated:");
scanf("%d",&n);
if(n==1)
{
printf("\n FIBONACCI SERIES\n");
printf("%d",a);
}
else if(n==2)
{
printf("\n FIBONACCI SERIES\n");
printf("%d\t%d",a,b);
}
else
{
printf("%d\t%d",a,b);
for(i=3;i<=n;i++)
{
c=a+b;
a=b;
b=c;
printf("\t%d",c);
}
}
getch();
}
void main()
{
int a,b,c,i,n;
a=0;
b=1;
printf("Enter number of terms of the series to be generated:");
scanf("%d",&n);
if(n==1)
{
printf("\n FIBONACCI SERIES\n");
printf("%d",a);
}
else if(n==2)
{
printf("\n FIBONACCI SERIES\n");
printf("%d\t%d",a,b);
}
else
{
printf("%d\t%d",a,b);
for(i=3;i<=n;i++)
{
c=a+b;
a=b;
b=c;
printf("\t%d",c);
}
}
getch();
}
OR
void main()
{
int a,b,c,i,n;
clrscr();
a=0;
b=1;
printf("\n enter n for how many times generate series");
scanf("%d",&n);
printf("\n FIBONACCI SERIES\n");
printf("\t%d\t%d",a,b);
for(i=0;i<n;i++)
{
c=a+b;
a=b;
b=c;
printf("\t%d",c);
}
getch();
}
well, the for loop should be
for(i=1;i<=n-2;i++)
good one re, thank you
thanks..
Thanks!!!!!!!!!!!
void main()
{
int a,b,c,i,n;
clrscr();
a=0;
b=1;
printf("\n enter n for how many times generate series");
scanf("%d",&n);
printf("\n FIBONACCI SERIES\n");
printf("\t%d\t%d",a,b);
for(i=0;i<n;i++)
{
c=a+b;
a=b;
b=c;
printf("\t%d",c);
}
getch();
}
this is the best.........
#include
#include
void main()
{
int a,b,c,i,n;
clrscr();
a=0;
b=1;
printf("\n enter n for how many times generate series");
scanf("%d",&n);
printf("\n FIBONACCI SERIES\n");
printf("\t%d\t%d",a,b);
for(i=1;i<n;i++)
{
c=a+b;
a=b;
b=c;
printf("\t%d",c);
}
getch();
}
hey can u post flow chart for this !!! plzz
fibonacci series starts with 1 never with 0...
a= -1
b=1
sum = a+b
a=b
b=sum
fibonacci series
#include
#include
void main()
{
int i,n,c,a=0,b=1;
clrscr();
printf("enter the number");
scanf("\n%d\n",&n);
printf("\nFIBONACCI SERIES\n");
printf(%d\n%d\n",a,b);
for(i=3;i<=n;i++)
{
c=a+b;
a=b;
b=c;
printf("%d\n",c);
}
getch();
}
thank u..
can explain the running of loop?
//This program will print the fibonacci series by using the printf statement only once...have a close look!!!
fibonacci series
#include
#include
void main()
{
int i,n,c,a=0,b=1;
clrscr();
printf("enter the number");
scanf("\n%d\n",&n);
printf("\nFIBONACCI SERIES\n");
for(i=0;i<=n;i++)
{
printf("%d\n",a);
c=a+b;
a=b;
b=c;
}
getch();
}
can anyone tell how to write reverse fabonnaci series
#include
#include
void main()
{
int i,n,c,a=0,b=1;
clrscr();
printf("enter the number");
scanf("\n%d\n",&n);
printf("\nFIBONACCI SERIES\n");
for(i=n;i<n;i--)
{
printf("%d\n",a);
c=a+b;
a=b;
b=c;
}
getch();
}
idiot
making it complex
It's running successfully.......... thanks..
#include
main()
{
int n, first = 0, second = 1, next, c;
printf("Enter the number of terms\n");
scanf("%d",&n);
printf("First %d terms of Fibonacci series are :-\n",n);
for ( c = 0 ; c < n ; c++ )
{
if ( c <= 1 )
next = c;
else
{
next = first + second;
first = second;
second = next;
}
printf("%d\n",next);
}
return 0;
}
Hey Frnz I Have Simple Way To Print it And Hope u Like N try it
so let's begin
void main(){
int a,b,i,n;
clrscr();
n=10;
a=0;
b=1;
for(i=1; i<=n; i++){
a=a+b;
b=a-b;
printf("%d ",b);
}
getch();}
the value of 'n' Will Varies as the series wants to maximize
hi, u have oversimplified...
the series is 0,1,1,2,3,5,8... while ur program gives
0,1,2,3,5,8....
so the third term gets missing...
but good attempt....
i think it is best to use
for(couter=1;counter<=N-2;counter++) loop....
:-)
the program is wrong.. publish the correct coding;;;;
u have to give for loop as for(i=2;i<n;i++)
remaining thnks are ok................
/* Fibonacci Series c language */
#include
main()
{
int n,a=0,b=1,c,d;
printf("Enter the number of terms\n");
scanf("%d",&n);
printf("First %d terms of Fibonacci series are :-\n",n);
for(d=0;d<n;d++)
{
if (d<=1)
c=d;
else
{
c=a+b;
a=b;
b=c;
}
printf("%d\n",c);
}
getch();
}
Other way without using "if else"
/* Fibonacci Series c language */
#include
main()
{
int n,a=0,b=1,c,d;
printf("Enter the number of terms\n");
scanf("%d",&n);
printf("First %d terms of Fibonacci series are :- \n",n);
printf("%d\n%d\n",a,b);
for(d=0;d<n-2;d++)
{
c=a+b;
a=b;
b=c;
printf("%d\n",c);
}
getch();
}
/* Fibonacci Series c language */
#include
main()
{
int n,a=0,b=1,c,d;
printf("Enter the number of terms\n");
scanf("%d",&n);
printf("First %d terms of Fibonacci series are :- \n",n);
printf("%d\n%d\n",a,b);
for(d=0;d<n-2;d++)
{
c=a+b;
a=b;
b=c;
printf("%d\n",c);
}
getch();
}
if i enter the no 1 than it will print 0 and 1 both in place of zero
i think it's not proper output
All above programs are starting with 0 and 1, what if we want another values say -1 or other integer ? Try this one !
#include
#include
int main(void)
{
int a,b,c,i,n;
printf("Enter first number: ");
scanf("%d", &a);
printf("\nEnter the second number:");
scanf("%d", &b);
printf("\nHow many times does you want the series:");
scanf("%d",&n);
if(n==1)
{
printf("\nFibonacci series is:\t%d", a);
}
else if(n==2)
{
printf("\nFibonacci series is:\t%d\t%d", a,b);
}
else
{
printf("\nFibonacci series is:\t%d\t%d", a,b);
for(i=2; i<n; i++)
{
c= a+b;
a= b;
b= c;
printf("\t%d", c);
}
}
getch();
}
#include
main()
{
int i,n,a,b;
printf("enter n terms");
scanf("%d",&n);
printf("fibonacci siries\n");
for(i=0;i<n;i++)
{
a=a+b;
b=a+b;
printf("%d %d",a,b);
}
}
Its simplest n perfect code...!!!
int main()
{
int a, b, fib, n=10,i;
a=0;b=1;
for (i=0;i<n;i++)
{
printf("fib %d\n", a);
fib = a+b;
a=b;
b=fib;
}
return 0;
}
#include
#include
void main()
{
int a,b,c,i,n;
a=0;
b=1;
printf("Enter number :");
scanf("%d",&n);
if(n==1)
{
printf("\n fibonacci series\n");
printf("%d",a);
}
else if(n==2)
{
printf("\n fibonacci series\n");
printf("%d\t%d",a,b);
}
else
{
printf("%d\t%d",a,b);
for(i=3;i<=n;i++)
{
c=a+b;
a=b;
b=c;
printf("\t%d",c);
}
}
getch();
}
for(i=0;i<n-2;i++)
Jst Change the for loop
for(i=0;i<n-2;i++)
#include
void main()
{ int n,i,a,b,c;
printf("enter the range");
scanf ("%d",&n);
for(i=o;i<=n;i++)
{c=a+b;
a=b;
b=c;
printf("the fibonaci series is=%d",c)
}
getch();
}
logic is correct and simple but it's not working.
void main()
{
int a=-1,b=1,c,i;
scanf("%d",&n);
for(i=0;i<n;i++)
{
c=a+b;
a=b;
b=c;
printf("%d\t",c);
}
getch()
}
#include
#include
main()
{int a,b,i,n;
a=b=1;
printf("enter number of times u want to print fibb series");
scanf("%d",&n);
for(i=0;i<n;i++)
{if(i<=1)
printf("%d",1);
c=a+b;
a=b;
b=c;
printf("%d",c);
}
getch();
}
it will print
1 1 2 3 5 7 12 19.....
No we can't write this code without intiala'n.
void main()
{
int i,n;
clrscr();
printf("\n enter n for how many times generate series");
scanf("%d",&n);
printf("\n FIBONACCI SERIES\n");
for(i=0;i<n;i++)
{
cout<<fabo(i)<<" ";
}
getch();
}
fabo(n)
{
if(n==0)
return 0;
if(n==1)
return 1;
else
return fabo(n-1)+fabo(n-2);
}
}
I dont know if u right...but what we were taught was starting from zero itself...well maybe u r right....lets see....
#include
void main(){
int no,x=1,y=1,z,i;
printf("Enter number :");
scanf("%d",&no);
for(i=2;i<no;i++)
{
z=x+y;
x=y;
y=x;
}
printf("%d",Z);
getch();
}
}
chek out this as well : c program to find fibonacci series using recursion
2. Draw the flowchart and write c program to display Fibonacci series numbers
can u wtite a code to print the fibonacci series within a specified range by the user. like if user enters 10 as the range,program should print 0,1,1,2,3,5.8
