Fibonacci Series using C

 

Fibonacci Series Using C program

C Program:

#include<stdio.h> #include<conio.h> int main() { int i,n,temp,t1,t2; printf("enter the no.of terms:"); scanf("%d",&n); t1=0; t2=1; for(i=0;i<=n;i++) { printf("%d ",t1); temp=t1+t2; t1=t2; t2=temp; } return 0; }

Output 1:

Output 2:

From the above program,

ü Let n=5.

i=0	i<=n	Print t1	temp=t1+t2	t1=t2	t2=temp	i++
0	0<=5	0	temp=0+1 temp=1	t1=1	t2=1	1
1	1<=5	1	temp=1+1 temp=2	t1=1	t2=2	2
2	2<=5	1	temp=1+2 temp=3	t1=2	t2=3	3
3	3<=5	2	temp=2+3 temp=5	t1=3	t2=5	4
4	4<=5	3	temp=3+5 temp=8	t1=5	t2=8	5
5	5<=5	5	temp=5+8 temp=13	t1=8	t2=13	6
6	6<=5 false	Doesn’t execute

ü final output will be as 0 1 1 2 3 5.
