No entiendo bien la pregunta. ¿Sintácticamente correcto? ¿Correcto
desde el punto de vista de estilo?

Primero. La segunda condición debería ser (var==7) ¿verdad?

Segundo. Si se quiere comparar con muchos valores parece un poco
largo.

Alternativa 1:

switch (var) {
  case 3:
  case 7:
  case 15:
	std::cout << "El valor es 3, 7 o 15" << std::endl;
}

Alternativa 2: Personalmente me gusta más

int v[] = {3, 7, 15};
int * end = v + sizeof(v)/sizeof(v[0]);
if ( end != std::find(v, end, var)) {
	std::cout << "El valor es ";
	std::copy(v, end, std::ostream_iterator<int>(std::cout, " "));
}
