Array References
| Scheme: | (vector-ref v i) |
| Pascal, C++, Java: | v[i] |
| Scheme: | (vector-set! v i value) |
| Pascal: | v[i] := value |
| C++, Java: | v[i] = value; |
Arrays must be declared before they can be used:
| Scheme: | (define myarr (make-vector 100)) |
| Pascal: | var myarr: array[0..99] of integer; |
| C++: | int myarr[100]; |
| Java: | long[] myarr = new long[100]; |
Indexing of arrays begins with 0 in Scheme, C++, and Java; the initial index is specified in Pascal.
