Fibonacci Sequence up to 10

 First few numbers: 0,1,1,2,3,5,8,13,21,34

Sequence and Formula:

The sequence starts with f=0 &  f1=1             

 Every subsequent number is by adding the two numbers before it.

f2= 0+1 -> 1  1+1 ->2  1+2 -> 3 ........

   f2=f1+f        

   f=f1 

   f1=f2

 #include<stdio.h>
main()
{
       int f=0,f1=1,f2=0,i;
       printf("\n%d\t%d",f,f1);
       for(i=3;i<=10;++i)
      {
            f2=f1+f;
            printf("\t%d",f2);
            f=f1;
            f1=f2;
      }
}
