program To print the Fibonacci series for 1 to n value

#include<stdio.h> void main()

{

int a,b,c,n,i; clrscr();

printf(“enter n value”); scanf(“%d”,&n);

a=0;

b=1;

if(n==1)

printf(“%d”,a); else

if(n==2)

printf(“%d%d”,a,b); else

{

printf(“%d%d”,a,b);

//LOOP WILL RUN FOR 2 TIME LESS IN SERIES AS THESE WAS PRINTED IN ADVANCE

for(i=2;i<n;i++)

{

c=a+b;

printf(“%d”,c);

a=b;

b=c;

}

getch();

}

}

Output:

2. Enter n value : 5

0 1 1 2 3

3. Enter n value : 7

0     1 1 2 3 5 8

4. Enter n value : -6

0     1

Conclusion : The program is error free

VIVA QUESTIONS:

1)    What is Fibonacci series ?

Ans: A fibonacci series is defined as follows  

 The first term in the sequence is 0

 The second term in the sequence is 1

 The sub sequent terms 1 found by adding the preceding two terms in the sequence Formula: let t1,t2,…………tn be terms in fibinacci sequence

  t1=0, t2=1 tn=tn-2+tn-1……where   n>2

2)     What are the various types of unconditional statements?

 Ans:   goto,Break and continue

  3)What are the various types of conditional statements?

  Ans: if , if else ,switch statements
