注释转换--

C语言的注释 -> C++的注释

C语言的注释 /* xxxxx */

C++的注释 //xxxxx

// 1.一般情况
/* int i = 0; */

// 2.换行问题
/* int i = 0; */int j = 0;
/* int i = 0; */
int j = 0;

// 3.匹配问题
/*int i = 0;/*xxxxx*/

// 4.多行注释问题
/*
int i=0;
int j = 0;
int k = 0;
*/int k = 0;

// 5.连续注释问题
/**//**/

// 6.连续的**/问题
/***/

// 7.C++注释问题
// /*xxxxxxxxxxxx*/

// 8.C注释本身不匹配
/* int i = 0;
