Question

Say I have a type edge:

struct edge
{
    long long weight;
    int dest;
    inline bool operator<(const edge& other) const
    {
        return weight > other.weight;
    }
};

In G++ 4.1.2 (CentOS) I can safely do:

edge e = (edge){0, 1};

But on MSVC++ 2010, the same code causes:

test.cpp(57) : error C2059: syntax error : '{'
test.cpp(57) : error C2143: syntax error : missing ';' before '{'
test.cpp(57) : error C2143: syntax error : missing ';' before '}'

Is there a way to do this in MSVC++ compiler?

I suggest having a constructor:

struct edge  {
   long long weight;
   int dest;
   edge(long long w, int d): weight(w), dest(d) {};
   inline bool operator<(const edge& other) const {
    return weight > other.weight;
   }
};

then use

edge e (0,1);
