Thread: call a function

My program prints out Fibonacci_number(0,1,1,2,3,5). The program is ok.
My problem:I want to take a number from Fibonacci_number(0,1,1,2,3,5)
and multiply whit 10. ex: I want to take 3 and multiply with 10.
I tried to write another function and call a Fibonacci_number from fib(int k)
and then multiply it whit 10.
How can I call an exact Fibonacci_number.

Code:

int fib(int k)
{
      
	  int my_nbr=0;
	  int f;
	  
          int  nbr1 = 0;
          int  nbr2 = 1;
          printf("0,1");

       
      for (f = 2; f < k; ++f)
       {
           printf(",%d", nbr1 + nbr2);
		     

           my_nbr= nbr2;
           nbr2 = nbr2 + nbr1;
           nbr1 = my_nbr;

		
       }
  printf("\n");
 
}

int main(void)
{
   fib(6);
  
   return 0;
}
