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:
