c++换行符有哪些
\n 换行，光标移到下一行的开头；
endl，把缓冲槽的内容输出到控制台；
\r 回车，光标移到当前行的开头，不会换到下一行，如果接着输出的话，本行以前的内容会被逐一覆盖；
#include <iostream>
using namespace std;
int main()
{
cout << "this is the first line\n";
cout << "this is the second line\r";
cout << "this is the third line\n";
cout << "this is the fouth line\r";
cout << "this is the fifth line\n";
cout<<"First"<<"\n"<<"Second"<<endl;
cout<<"First123"<<"\r"<<"Second"<<endl;
cout<<"这是换"<<endl<<"行符";
return 0;
}结果：
this is the first line
this is the third linee
this is the fifth line
First
Second
