    Struct member manipulation

    I work on a system that communicates with other systems via messages. Those messages are defined in a spec and every word must be exactly as defined. To accomplish this Ada allows me to define the fields of my record to specific words in memory. Will C++ allow me to accomplish this same task and if so could someone post an example

    Code:
    word = 4;
    
    type Msg_Type1 is record
       x: Some_Type;
       y: Another_Type;
       z: Another_Type;
    end record;
    
    // ada allows me to rep out my record using the 'for use' clause
    for Msg_Type1 use record
       x at 0*word range 0..31;
       y at 1*word range 0..15;
       z at 1*word range 16..31;
    end record;
