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*//*asdasasdasdasdasdsadasd*/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*/
