c++換行符有哪些
\n 換行,游標移到下一行的開頭;
endl,把緩衝槽的內容輸出到控制檯;
\r 回車,游標移到當前行的開頭,不會換到下一行,如果接著輸出的話,本行以前的內容會被逐一覆蓋;
#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<<"這是換"<<endl<<"行符"; return 0; }
結果:
this is the first line this is the third linee this is the fifth line First Second Second23 這是換 行符 Presss any key to continue
內容補充:
關於遇到的問題例項:
遇到\r獲取\n的時候,替換為\0.
#include<string.h> #include<stdio.h> int main(int argc,char *argv[]) { char str[128]; while (fgets(str,127,stdin)) { char *tmp = NULL; //去掉換行符 if (tmp = strstr(str,"\n")) *tmp = '\0'; //去掉回車符 if (tmp = strstr(str,"\r")) *tmp = '\0'; printf("---%s---\n",str); } return 0; }
