为什么在编译时直接略过了getline

xjhjtz0320 @ 2024-11-29 19:25:19

if(zfccz=="in"){
                    cout<<"请输入字符串";
                    getline(cin,strzfc);
                    cout<<123; 
                }

@xjhjtz0320 疑似换行被吃掉了

试一下 getline(cin>>ws,strzfc);

@xjhjtz0320 清空缓冲区，cin.sync()

@xjhjtz0320应该是 getline读取到了缓冲区的字符？

@xjhjtz0320 有可能读入了换行符，cin.ignore(1000,'\n')滤一下换行符

@xjhjtz0320 可以了，完整代码如下：

if(zfccz=="in"){
                    cout<<"请输入字符串";
                    cin.sync();
                    getline(cin,strzfc);
                    cout<<123; 
                }

getline读到了末尾的换行
