I'm playing with templates in Symantec C++ and I have come across somthing that I can't understand. The following is an abridged version of some code that comes from a C++ book. The program won't compile if the template function's parameter is constant. It will compile if it is not constant. I an error stating that WriteAll1 is already defined. I get other errors such as ';' expected, undefined identifier 'a' and a warning, value of expression not used. If I remove the 'const', it all goes away. I can't see anything syntactically wrong with the version with the const parameter. Any ideas? // Ed // Display vector contents template<class T> void WriteAll1(const Vector<T> &a) { int i; cout << "Vector contents (" << a.GetNElem() << " items):\n"; for (i = a.GetMin(); i <= a.GetMax(); ++i) cout << " vector[" << setfill(' ') << setw(2) << setiosflags(ios::showpos) << i << resetiosflags(ios::showpos) << "] == " << a[i] << endl; } void SomeFunction() { Vector<float> dVector(low, high); // do something … WriteAll1(dVector); Vector<float> copy(dVector); // do some more stuff … WriteAll1(copy); }
