the fibonnacci numbers are {1,1,2,3,5,8,11,19,30,49,79,128 ..... infinity}

try

#include<stdio.h>

#include<math.h>

int main()

{

int a,b

float input

printf("Enter number: ");

scanf("%f, &input");

for(a=1;a=100000;a++);{

b=+a;

if b ==input{

Break;

printf("The number that you chose, %f, is a Fibonacci number", input);

}

a=b;

}

return 0;

* I haven't actually tested this program so edit it to make it work if it doesn't *

Also, don't forget the indenting.

Write a program to print the Fibonacci series in php upto input value using recursive function?

The Fibonacci sequence uses recursion to derive answers. It is defined as: F0 = 0 F1 = 1 Fn = F(n - 1) + F(n -2) To have this sequence printed by a php script use the following: function fibonacci($n) { if($n 1) return 1; //F1 else return fibonacci($n - 1) + fibonacci($n - 2); //Fn } This recursive function will print out the Fibonacci number for the integer n. To make it print out all the numbers in a particular set add this to your script. for($i = 0; $i &lt; 15; $i++) { echo fibonacci($i) . "&lt;br /&gt;"; } So your final result would look like. &lt;?php function fibonacci($n) { if($n 1) return 1; else return fibonacci($n - 1) + fibonacci($n - 2); } for($i = 0; $i &lt; 15; $i++) { echo fibonacci($i) . "&lt;br /&gt;"; } ?&gt;
