Question

I’m having a difficult time understanding how to get these bits in the right order

my goal:

given the following inputs

char id = 0x02; //in binary => 0010
char somethingElse = 0xF; //in binary => 1111

how can I obtain the following output

char result = ?; //in binary 0010 1111 (id somethingElse)

Answer 1

char id = 0x02; //in binary => 0010
char somethingElse = 0xF; //in binary => 1111

char result = (id<<4) | somethingElse;
