Correct way to check if a type is Nullable [duplicate]

Awkward way of executing JavaScript code [duplicate]
...
var a = (function() {
return foo(bar);
})();
In this case this is really unnecessary, but this is not wrong and it will not throw an error.

或者将distance放在一个命名空间中,例如：
namespace foo
{
double distance(int a, int b)
{
return fabs(a-b);
}
}
int main()
{
foo::distance(x,y); //now you're calling your own distance function.
}
或者不使用命名空间std,显式声明std::vector...
