C language feature in which a struct may contain as its last member an array with no specified size
C struct data types may end with a flexible array member[1] with no specified size:
structvectord{shortlen;// there must be at least one other data memberdoublearr[];// the flexible array member must be last// The compiler may reserve extra padding space here, like it can between struct members};
Typically, such structures serve as the header in a larger, variable memory allocation:
structvectord*vector=malloc(...);vector->len=...;for(inti=0;i<vector->len;i++)vector->arr[i]=...;// transparently uses the right type (double)
