Limpar Buffer cin


Recommended Posts

Boas Pessoal,

Estou com um daqueles problemas ridículos  :wallbash:, que é, tenho uma série de "cout's" e "cin's" todos misturados, mas como não limpo o buffer do cin, às vezes o '\n' fica lá e o programa salta algumas instruções 'cin'....  ?

Encontrei isto na net:

// Ignore to the end of line
cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n')

Mas ao compilar dá-me estes erros (e é na segunda linha do exemplo anterior):

error: ‘numeric_limits’ is not a member of ‘std’

error: expected primary-expression before ‘>’ token

error: ‘::max’ has not been declared

Será que me falta algum include?!  ?

cumps  👍
