The 
continue statement
causes control to pass to the loop-continuation portion of the
smallest such enclosing 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: ;
}
