for multiple dimension array, is it possible to define an operator [][](say for two dimensions)? I try to define it as int & operator[][] (int, int); which g++ complains about it. any idea or just sth is wrong with my try? -- Duanyang Guo | (212)939-7098(O), 663-8904(H) CS Dept, Columbia Univ. | Rm 625, CEPSR New York, NY 10027 | Email:duanyang@cs.columbia.edu
