in vb anything that isnt 0 evaluates to true, is this the same in d?

//example

char[] foo;
foo.length = 1;

if (foo.length) {

}

//or

uint x;
x = -1;
if (x) {  }

//or
while (x) { }


thanks

Yes, it's the same in C and C++ as well.  One difference is that the literal true = 1 in these languages. In VB the literal true = -1;  It's particularly useful for pointers, which are null (0) if they don't have anything in them.

int* p;

if (p)
{
   //There's something in p
}
