關於C語言的指標陣列與指標陣列的個人理解
一 指標陣列與指標陣列 1，指標陣列 顧名思義，即乙個元素全部是指標的陣列，其形式與普通陣列相似，形式如 a n 在理解指標陣列的使用方式前，我先來說下我個人對陣列的理解。比如一維整形陣列 形如int a 3 其實是乙個具有3個整形元素的變數 二維整形陣列 形如int a 4 3 可將其視為有a 4...
C語言 陣列指標和陣列指標的理解
陣列指標和指標陣列如何分辨呢看他後面的側重 例如 分解 int a 3 int 3 a 指標陣列 int b 3 int 3 b 陣列指標 片段 這段 定義了乙個陣列指標和乙個陣列指標，利用指標的偏移來做測試 include int b 3 陣列指標 char str1 good char str2...
C 指標與陣列的理解
參考文章 雖然部分內容有錯誤，但是整體講的不錯 int a 3 輸出如下 陣列a的元素型別為int，因此相鄰兩個元素的位址相差4個位元組。每個元素的位址由16個十六進製制數表示，每個十六進製制數可由4個二進位制數表示，8個二進位制數占用乙個位元組的記憶體空間。因此元素的位址 即指標變數 占用8個位元...
