Fibbonacci series

Fibonacci series

// Fibonacci Series
0,1,1,2,3,5,8,13,21,34,55,89,144......

Fibonacci series

#fibonacci series is special type of sequence
#fibonacci series is somethinng liket this-->
#0,1,1,2,3,5,8,13,21,34,55,89.......
#addition of former two succesive number results in the third element.
#in simple way as given in above series that 0,1,1--> where 0+1=1 e,i; 1
#example: 2,3,5 addition of 2 and 3 results in latter element in sequence e,i 5
8,13,21 :  8 + 13=21
34,55,89:  34 + 55=89

Fibbonacci series

 1, 1, 2, 3, 5, 8

#include <stdio.h>

void main()
{
    int s1=0,s2=1; //initializing first two numbers 
    int nextNum=0,SumUpto=0;
    printf("\n\n\tPlease enter number up to which print Fibonacci series is required \t");
    scanf("%d",&SumUpto);
    //here assuming user will enter value more than 1 
    //printing first two numbers
    printf("\n\tfibbonacci Series up to %d is ",SumUpto);
    printf("\n\n\t%d  %d",s1,s2);
     for(nextNum=2;nextNum<=SumUpto;)
    {    
        s1=s2;    
        s2=nextNum; 
        printf(" %d",nextNum); 
        nextNum=s1+s2;
