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 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\0.
#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 = '\0'; //去掉回车符 if (tmp = strstr(str, "\r")) *tmp = '\0'; printf("---%s---\n", str); } return 0; }
