分離式編譯注意問題：

(1)關(guān)于函數(shù)的全局變量不能定義在自定義庫lib.h中，因?yàn)槿缦略?#xff0c;

假設(shè)定義在庫lib.h中，那么分離式編譯function.c?和main.c都各自需要一個(gè)lib.h，但是這樣編譯時(shí)候就會(huì)產(chǎn)生每個(gè)函數(shù)重復(fù)定義錯(cuò)誤。所以，全局變量必須此時(shí)放在function.c中

(2)function.c程序如果循環(huán)體內(nèi)有三個(gè)getchar()，那么如果中途需要continue，那么必須放在三個(gè)getchar()之后。使用循環(huán)必須注意循環(huán)的”核心“.因?yàn)間etchar() 不會(huì)放過任何一個(gè)字符，例如"\n"，所以每次的結(jié)束循環(huán)動(dòng)作必須放在三個(gè)getchar()之后，否則"\n"會(huì)被不正確的地方讀入。

總結(jié)
