C++ Question

c++ vector initialization

I have been using the following vector initialization with values in Code::Blocks and MingW compiler:

vector<int> v0 {1,2,3,4};

After that I had to move the code to a visual studio project (c++) and I tried to build. I got the following error:

local function definitions are illegal

Visual Studio compiler does not support this kind of initialization?

How do I need to change the code to make it compatible?

I want to initialize vector and fill it with values at the same time, just like an array.

Visual C++ does not yet support initializer lists.

The closest you can get to this syntax is to use an array to hold the initializer then use the range constructor:

std::array<int, 4> v0_init = { 1, 2, 3, 4 };
std::vector<int> v0(v0_init.begin(), v0_init.end());
