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 linen";
cout << "this is the second liner";
cout << "this is the third linen";
cout << "this is the fouth liner";
cout << "this is the fifth linen";
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 Second23 这是换 行符 Presss any key to continue
内容补充:
关于遇到的问题实例:
遇到r获取n的时候,替换为 .
#include<string.h>
#include<stdio.h>
int main(int argc, char *argv[])
{
char str[128];
while (fgets(str, 127, stdin)) {
char *tmp = NULL;
//去掉换行符
if (tmp = strstr(str, "n"))
*tmp = ' ';
//去掉回车符
if (tmp = strstr(str, "r"))
*tmp = ' ';
printf("---%s---n", str);
}
return 0;
}
