Input Output in ATmega

[nXn]

I am new to Atmega .....
I am using AVR studio for programing my atmega 16
But when I give the below statement it doent work...

if(PINC.0==1)
PORTB=0x01;

It doent show any compiling error ....
but when burned in a microcontroller it doent glow the LED which is connected to PORTB.......

Did you set your DDR registers properly, like:

DDRB = 0x01;
DDRC = 0;

Hi,
I think your code should be:

if (PINC & (1<<0))
   PORTB = 0x01;

instead of:

if (PINC.0 == 1)
PORTB = 0x01;

Added after 1 minutes:

Try it and let me know how it works out for you.
Tahmid.

If you are using winavr, then try:

if(bit_is_set(PORTC, 0))
