Assembler and Programming

Given is the following Assembler program of an $8-$Bit Atmel AVR microcontroller. The used constants are decimal numbers.

loop:

LDI $r17,0$

LDI $r19,10$

MOV r$20,$ r$17$

CP r$20,$ r$19$

BRGE end

INC r$20$

LDI r$16,0$

SUB r$16,$ r$20$

ADD $r17,r16$

INC $r20$

ADD r$17,$ r$20$

RJMP loop

end:

ret

Implement a C program that represents the functionality of the above shown Assembler program. Use a main function as frame for your implementation.

int main$()$

$...$ your program.
