You can create a an array first that you then use with the vector constructor that takes iterators.

Example:

#include <vector>

template<typename T, size_t N>
size_t size(const T(&)[N]) {
    return N;
}

int main() {
    int arr[] = {12,24,56,45,32,76};

    std::vector<int> v(arr, arr+size(arr));
}

I also got this Issue & has been fixed.

In Devc++ ,

Go to

Tool > Compiler Options > Settings > Code Generation

& Set "Language Standard" to "ISO C++11"

No need any other changes.See this
