Any body print fabnoci series using for loop with using two variable in c

Question

In c

Answer 1

#include <stdio.h>

int main() {
n,i,a=0,b=1;
printf ("enter number of terms");
scanf("%d",&n);
printf ("%d",a);
printf("%d",b);
for(i=1;i<=n;i++)
{
i=a+b;
printf("%d",i);
a=b;
b=i;

}
return 0;
}

Answer 2

show your attempt first

Answer 3

Interstingly, you can also use maths to directly calculate nth Fibonacci number instead of finding it constructively

Answer 5

Using recursion

import java.util.*;

public class Program
{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);

int n = sc.nextInt();

for (int i = 0; i < n; i++)
System.out.print(fab(i) + " ");
}

static int fab(int n) {
if (n < 2) {
return 1;
} else {
return fab(n - 1) + fab(n - 2);
}
}
}

Answer 16

Ok I am trying to use two variables

Answer 17

fibonacci sequence is formed by sum of 2 numbers.
think it is
a=0,b=1
for 1...n
print(b) // 1, 1, 2, 3
b+=a
a=b-a

however clearly at least 4 variables since you will need loop counter and n counts :)
to get rid of extra variables, just make it an infinite loop for(;;) ;)
0 variables would be possible assuming you know the number of digits to display.
Would just be printing hardcoded string lol.
why a=b'-a. At this point b'= b+a. So substituting a=b'-a -> b+a-a -> so b
