C programming, all questions please

11. An 8-bit data registers has following data. Each bit corresponds to an output pin that connects to a LED. A 0 indicates low output voltage that turns off a LED. A 1 indicates a high output voltage that turns on a LED. DATA R Bits Let DATA R store this value. Write no more than 5 lines of code to clear bits 1 and 2. You must use hex values in the code 12. Same as problem 11. DATA R Bits Write no more than 5 lines of code to set bits 0 and 3. You must use hex values in the code. 13. Same as problem 11 and 12. DATA R Bits Let DATA_ R store this value. Write no more than 5 lines of code to toggle bit 4. You must use hex values in the code
