c++ - 错误: 'operator>>' 不匹配(操作数类型为 'std::basic_istream<char> cin>> salary >> endl；^

Question

我有以下代码:

#include <QCoreApplication>
#include <iostream>
using namespace std;

int main(int argc, char *argv[])
{
    int salary;
    int childeren;
    cout << "please type base salary=";
    cin>> salary >> endl;
    cout<< "plz type count your childeren=";
    cin >> childeren >> endl ;
    int Totalsalary=salary + childeren*10;
    cout<< Totalsalary<< endl;
    return 0;
}

我试图理解创建错误:

no match for 'operator>>' (operand types are 'std::basic_istream::__istream_type {aka std::basic_istream}' and '') cin>> salary >> endl; ^

Answer 1

std::endl 用于创建行尾和刷新流缓冲区。它应该与 std::cout 一起使用，而不是与 std::cin 一起使用。

所以更正你的下一行

cin>> salary >> endl;

到

cin>> salary;
