6 Statements [stmt.stmt]

6.6 Jump statements [stmt.jump]

6.6.2 The continue statement [stmt.cont]

1

The continue statement shall occur only in an iteration-statement and causes control to pass to the loop-continuation portion of the smallest enclosing iteration-statement, that is, to the end of the loop. More precisely, in each of the statements

while (foo) {
  {
    // ...
  }
contin: ;
}

do {
  {
    // ...
  }
contin: ;
} while (foo);

for (;;) {
  {
    // ...
  }
contin: ;
}

a continue not contained in an enclosed iteration statement is equivalent to goto contin.
