Fibonacci sequence

Question

hi,

   Why "Fibonacci (day-1)" and "Fibonacci (day-2)" are not the same recursive procedure?

Code is as follows:

#include<stdio.h>

int Fibonacci(int day)

{

 if(day==1||day==2) 

 return 1;

 else 

return Fibonacci(day-1)+Fibonacci(day-2);

}

void main()

{

  printf("Fibonacci sequence:%d\n",Fibonacci(7));

}

thank.
