size_t in c++?

[saneman]

In a file I have made:

size_t bb;
bb = 3u;
printf("bb %d\n");

which prints:

bb 2280640

But what is 'u' and why does it print the above number?

Prints garbage from stack, there is no argument given for %d.
Should be : printf("bb %d\n",bb);

Even then, %d and size_t don't match. Use %zu for size_t, as it might be
larger than an int.

It's the C99 format specifier for size_t.
