How can we do this In assembly we do mov P0, #10001000B
But in Keil how can we do this P0 = 10001000, in binary not by P0 = 0x11; Thank you!
This has nothing specifically to do with Keil - it is standard 'C'.
You need to look in any 'C' textbook for the number base representations supported by the 'C' programming language...
