In Zig? It would allocate stack space for a new variable a, and add b and the d field of c together and insert that value into the memory location that a reserved. In D or Python or anything that allows for properties, it would be allocating a where-ever the language allocates stuff, then calling an infix function '+' which could be anything depending on the language including starting up a JVM in the background for god knows what reason, and calls it with the arguments b and the result of calling the property function d of the object c.
