hi, i'm having trouble compiling this code: SparseMatrix.h: [CODE] #ifndef SPARSE_MATRIX #define SPARSE_MATRIX #include <ostream> class SparseMatrix { //class data ... SparseMatrix operator+(const SparseMatrix& rhs) const; SparseMatrix operator*(const SparseMatrix& rhs) const; }; ostream& operator<<(ostream& out, SparseMatrix& rhs); #endif [/CODE] SparseMatrix.cpp: [CODE] #include "SparseMatrix.h" ostream& operator<<(ostream& out, SparseMatrix& rhs) { ... …
