注释转换

简介

将C++注释转换成C语言注释

代码块

input.c C++的注释风格

int num = 0; /*int i = 0;*/ /*int i = 0;*/int j = 0; /*int i = 0;*/ int j = 0; /*int i = 0;/*123456*/ /* asdas asdasd asdasd sadasd */int k = 0; /*dsfsd*//*gdfg*/ /***/ // /*xxxxxxxxxxx*/

output.c C的注释风格

int num = 0; //int i = 0; //int i = 0; int j = 0; //int i = 0; int j = 0; //int i = 0;/*123456 // //asdas //asdasd //asdasd //sadasd // int k = 0; //dsfsd //gdfg //* // /*xxxxxxxxxxx*/
