Write a c programme to check whether given number is Fibonacci?

Answer 1

#include<iostream.h>

#include<conio.h>

void main()

{

long int n,a=0,b=1;

cout<<"dear user Enter number as u wish";

cin>>n;

while(n>0)

{

c=a+b;

cout<<"c<<"\t\t";

a=b;

b=c;

}

getch();

}

Answer 2

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.
