各位学长，能不能帮小妹做个作业啊，把C++转换为C语言

又是学生党！你知道 C 和 C++ 的区别吗？为什么这段代码叫 C++，又没有用到 C++ 最有特点的：类 呢。
你只能自己动手。
找对应的函数替换，自己对手
把cout换成printf，把头文件中的iostream换成stdio.h，把using namespace std去掉就是C的了
输入输出函数不一样而已，自己改一下
很简单，将cout写成printf就可以了。另外C语言用/**/的注释。
也真是无语啊！
把#include后面的iostream改成stdio.h
cout改成printf
setw(8) 这些都是c++的格式化输出，你搜一下就知道printf中的对应代码了
你把类class变成结构体
吧cout变成printf
把cin变成scanf
把iostream 变成stdio.h
把using namespace std去掉
