Consider the following program:

Suppose this program is named as y.cpp
When this program is compiled under Redhat Enterprise Linux
Workstation, as
g++ -std=c++98 -pedantic -Wall -Wextra y.cpp
I am getting the following compilation error:
y.cpp: In member function `T& Vec<T>::operator[](int)':
y.cpp:14: error: there are no arguments to `at' that depend on a
template parameter, so a declaration of `at' must be available
However under VC++ Express Edition 2005, it compiles well without any
warning or error.
Kindly explain what is wrong with the above program and help me in
fixing the compilation error with g++ under Linux
Hi,
you can try following one:
rather than using return at(i) use the following one:
return vector<T>::at(i)

"Oh, sure, all the time."
