i am only superficially aware of C++, so....
i recall that PL1 would allow a structure to contain variable length
elements (depending on a length parameter). With C i would
have to declare a pointer and allocate the memory.
Did PL1 allocate the vector inline? Does C++ do this?
Maybe a little visual aid would clarify:

C:

struct {

int vector_len;
int *vector_val;

};

C++:?
struct {

int vector_len;
int vector_val[0];
...
int vector_val[vector_len-1];
...
};
