第58章 《Coding Art》第13篇 char text[100];並沒有爲text單獨分配一個指針類型的變量內存
No Plagiarism!GtcnXPo57AD8v4mnHSdLposted on PＥNAＮＡ

在C语言中，使用 char text[100]; 分配一塊內存區域時，只是分配了100個byte的內存，而並沒有爲text分配一個char*類型的變量內存，如果我們用 &text 取text的地址，會發現它就是text本身，這就證明了沒有爲text分配一個指針變量的內存。必須用char *text2=text; 才能將text所在的地址寫入內存的指針變量中，然後用&text2才能取到char**類型的指針。如果想當然的用&text，得到的實際上是一個char*類型的變量，它的值與text相同。245Please respect copyright.ＰＥＮＡＮＡYVazdwQkTx
