Yes, while gotos are frowned upon, they're still allowed in C/C++.
Where to goto? A label, of course.

I wrote this:
#include <stdio.h>
void f() {
printf("f");
}
int main() {
goto f;
return 0;
}
foo.c:8:10: error: use of undeclared label 'f'
goto f;

1 error generated.
fun note: C-- has something like that! iirc it's like calling a function, but reusing the current stackframe:
jump f(expr1,. . .,exprn);

The concept is not so unique as you might think tho; the more commonly used term is "tail call".
re: C--, i think it's mostly used as a compiler IR. (notably in Haskell's GHC)
