這是我對書店的簡單代碼 代碼沒有任何問題。我正在使用DevC++來運行代碼,並在編譯後給出一個錯誤,說'獲取'沒有在此範圍內聲明&對於puts相同的錯誤。請幫幫我。dev(++)中沒有聲明gets()&puts()

你錯過了一個include:'#include'。這就是說......爲什麼在C++中使用gets(),puts()和char []而不是getline(),cout和string? –
你的問題是你必須使用它們,因爲你開始使用C風格的字符串。移動到'std :: string',你不需要C函數,因爲'cin'和'cout'和'string'一起工作良好。 –
「代碼沒有問題。」 - 你有什麼基礎? – hvd
