Is it possible to print a random number in C++ from a set of numbers with ONE SINGLE statement?

Let's say the set is {2, 5, 22, 55, 332}

I looked up rand() but I doubt it's possible to do in a single statement.

int numbers[] = { 2, 5, 22, 55, 332 };
int length = sizeof(numbers) / sizeof(int);
int randomNumber = numbers[rand() % length];
