Embedded systems always require the user to manipulate bits in
registers or variables. Given an integer variable a, write two code fragments.
The first should set bit 5 of a. The second shnuld clear bit 5 of a. In both
cases, the remaining bits should be unmodified.

第11题:
In a Frame Relay network, delay sensitive traffic is tagged with the discard eligible (DE) bit.
In an MPLS network, the three most significant bits of the DSCP or the IP precedence of the IP packet are copied into the MPLS EXP field.
In an MPLS network, the MPLS EXP bits are used to identify up to 16 CoS values.
The differentiated services code point (DSCP) field consists of the first three bits of the IP precedence field in the header of an IP packet.
The 802.1Q standard uses a three bit field referred to as the user priority bits (PRI) to mark packets as belonging to a specific CoS.
