No. In a ternary operator, both of the values must be expressions. continue is a statement, not an expression. Use an if statement instead.

I would say you can do it with while loop easily :

while(1){

if(i%3 == 0)
    i = i % 3;
}else{
    printf_s("no");
    break;
}

This will not work as the conditional operator is part of an expression whose value is either the second or third clause, and continue is a statement.

The conditional operator can be used in ways such as this:

days_in_february = is_leap_year() ? 29 : 28;

So now imagine if what you wanted was allowed. If you did this:

val = (i%3==0)? continue : (printf("no"));

Then what would value be set to if the condition was true? continue is not an expression and therefore doesn't "have a value" so such a statement wouldn't make sense.

You need to use a standard if statement to accomplish this:

if (i%3==0) {
    continue;
} else {
    printf("no");
}
