C語言實現(xiàn)動態(tài)順序表的實現(xiàn)代碼

順序表是在計算機(jī)內(nèi)存中以數(shù)組的形式保存的線性表，是指用一組地址連續(xù)的存儲單元依次存儲數(shù)據(jù)元素的線性結(jié)構(gòu)。線性表采用順序存儲的方式存儲就稱之為順序表。順序表是將表中的結(jié)點(diǎn)依次存放在計算機(jī)內(nèi)存中一組地址連續(xù)的存儲單元中。

靜態(tài)實現(xiàn)：結(jié)構(gòu)體內(nèi)部只需兩個成員，其中一個為固定大小(MAX)的數(shù)組，用來存放我們的數(shù)據(jù)。數(shù)組大小我們可以通過在頭文件中改變MAX的值來改變。

動態(tài)實現(xiàn)：在內(nèi)存中開辟一塊空間，可以隨我們數(shù)據(jù)數(shù)量的增多來擴(kuò)容。

來看看動態(tài)的順序表實現(xiàn)：
