Constructor (initializer_list)

[enterei]

hello this is my first post and i hope you can help me :)


at university we wrote a class simular to vector. it works my class works at university but not on my computer. in particular this constructor isnt working:
i include iostream
and use usesing namespace std;

header file:
Vector (initializer_list<double> );

Vector:: Vector(initializer_list <double> li){
max_sz=li.size();
sz=0;
if(max_sz) values = new double[max_sz];
else values = nullptr;
if (values){
for (const double& elem : li) values[sz++] =elem;
}
}

i use dev c++ 5.11, TDM-gcc 4.9.2

when i put gcc --version in my cmd it says 5.3.0

Are you are missing #include <initializer_list> in the header?

And, do not place using namespace std ; in the header file.
Use qualified names in the header. eg. Vector ( std::initializer_list<double> );

If you still get errors with gcc 5.3.0, post the entire contents of the header.

when i write "Vector ( std::initializer_list<double> );" its still the same error

when i include #include <initializer_list> i get this:

how can i be sure that my dev c++ uses gcc 5.3.0?

my dev c++ path links to mingw/bin

By default, your GNU compiler assumes that the program is written in a home-grown linux dialect of C++ based on the obsoleted 1998 C++ standard.

You need to explicitly enable C++11 support.
See: http://www.cplusplus.com/doc/tutorial/introduction/devcpp/

To insist on standard C++ conformance (to the extent possible), also specify -pedantic-errors

thank you so much

can now start to worry how i manage my homework ( still no idea about that^^)
