將c語言注釋轉換成c++注釋

標籤：c語言   c++   注釋   轉換   

可以分為7種情況
1.一般情況
/* int i = 0; */
2.換行問題
/* int i = 0; */ int j = 0;
3.匹配問題
/int i = 0;/*xxxxx/
4.多行注釋問題
/*
int i=0;
int j = 0;
int k = 0;
*/int k = 0;
5.連續注釋問題
////
6.連續的**/問題
/*/
7.C++注釋問題
// /xxxxxxxxxxxx/
轉換之後結果
1.一般情況
// int i = 0;
2.換行問題
// int i = 0;
int j = 0;
3.匹配問題
//int i = 0;/*xxxxx
4.多行注釋問題
//
//int i=0;
//int j = 0;
//int k = 0;
//
int k = 0;
5.連續注釋問題
//

6.連續的**/問題

7.C++注釋問題
