Why are hexadecimal numbers prefixed with 0x?
...400 translates to 6*16^3 + 4*16^2 + 0*16^1 +0*16^0 = 25600.
When compiler reads 0x6400, It understands the number is hexadecimal with the help of 0x term. Usually we can understand by (6400)16 or (6400)8 or whatever ..
For binary it would be:
0b00000001
Hope I have helped in some way.
