Yes.

For the second time, no it does not. A continue jumps to the end of the
loop body.
The C99 standard says:
6.8.6.2 The continue statement
Constraints
1 A continue statement shall appear only in or as a loop body.
Semantics
2 A continue statement causes a jump to the loop-continuation portion of
the smallest enclosing iteration statement; that is, to the end of the
loop body. More precisely, in each of the statements
while (/* ... */) {
/* ... */
continue;
/* ... */
contin: ;
}
do {
/* ... */
continue;
/* ... */
contin: ;
} while (/* ... */);
for (/* ... */) {
/* ... */
continue;
/* ... */
contin: ;
}
unless the continue statement shown is in an enclosed iteration
statement (in which case it is interpreted within that statement), it
is equivalent to goto contin;.
