//? 數(shù)組的定義
//? 當(dāng)需要保存很多"相同類型"的數(shù)據(jù)時(shí)就可以使用數(shù)組來(lái)保持\
? ? 用變量來(lái)保存的話會(huì)很復(fù)雜
//? 格式:元素類型 數(shù)組名稱[元素個(gè)數(shù)];
//? ? 元素類型: 就是數(shù)組中需要存儲(chǔ)的數(shù)據(jù)類型, 一旦指定, 數(shù)組中就只能存儲(chǔ)該類型的數(shù)據(jù)
//? ? 元素個(gè)數(shù): 就是數(shù)組中能夠存儲(chǔ)的數(shù)據(jù)(元素)的個(gè)數(shù)
