例如, 一個假設只接受非空 指針的函數, 可以寫: assert(p != NULL);當程式執行到該行時，若 p != NULL 則程式可以繼續執行；若        p == NULL ，則會秀出維護錯誤訊息的字串，並結束程式。        維護字串包含有：判斷式子、程式檔名及該行的行號。

C++算式由一或多個運算元(operands)和通常會有的一個運算子(operator)組成 每個output operator接收兩個運算元(operands); 左運算元必須是個ostream object, 右運算元則是待印值。outpot operator把右運算元寫至左運算元所示的ostream中 C++的每一個算式都會產生一個結果,通常就是把運算

1.const出現在星號左邊，代表被指物是常量。2.const出現在星號右邊，代表被指標自身是常量。 char greeting[] = "Hello";char* p = greeting; //non-const pointer, non-const dataconst char* p = greeting; //non-const pointer, c

摘要:一般我們要判斷奇偶數，都會想到用%，其實有更快的方法，不需要動用到除法原理:奇數的數值若以二進位來表示，其最右邊的位元必為1，而偶數最右邊的位元必為0，所以若使用1來與輸入的值作AND運算，因為 1除了最右邊的位元為1之外，其它位元都會是0，所以與輸入數值作AND運算所得的結果，最右邊的位元不是0就是1，其它部份都被0 AND運算遮掉了00000110     6
