C language Comment to C + + comment

Convert C language Comments to C + + annotations

/*......*/turn into//...

Test Case:

1. General Information

/* int a = 0; */

2. Continuous *

/***/

3. Line break issues

/* int b = 0; */int c = 0;

/* AAA */

int d = 0;

4. Matching issues

/*aaa/*bbb*/

/*int e = 0;/*xxxxxx*/

5. Multi-line annotations

/*

Aaa

Bbb

Ccc

*/int AA;

6. Continuous annotation

/*aaa*//*bbb*/

7.c++ Comments (read a line directly after encountering C + + comments)
