import core.stdcpp.vector;
import std.stdio;
void main()
{
    vector!double v = [1.0, 2.1];
    //double[] a = [];
    vector!string vs = ["33","44"];
    writeln(v[0]);
    writeln(vs[0]);
    //writeln(v);
}

这是一个示例,再来个:

import core.stdcpp.vector;
import std.stdio;

void foo(S s) {
    writeln(s.a[1]);
}

struct S
{
    vector!int a;
}

void main(){
    vector!int b=[20,33];
    S s=cast(S)b;
    foo(s);
}
