C语言实战项目（AI代码）

是的，你没有听错，用C语言编写一个简单的AI代码，功能十分简单，仅供娱乐，重要的是其中有几个实用性较强的自定义函数

废话不多说，先上代码

#include 
#include 
//转换大小写
void RemoveLetter(char* str);
//删除多余空格
void RemoveSpace(char* str);
//疑问词转换
void TurnInterrogativewords(char* str);
//问号转成感叹号
void TurnSymbol(char* str);
//第一人称改第二人称
void TurnFirstperson(char* str);
