打印字符串数组元素c ++

Question

尝试从我的字符串数组中打印元素。标记评论错误的位置。

获取错误：

1. IntelliSense: no operator "<<" matches these operands operand types are: 
   std::ostream << const std::string
   

2. error C2679: binary '<<' : no operator found which takes a right-hand operand
   of type 'const std::string' (or there is no acceptable conversion)

#include <iostream>
using namespace std;

int main()
{
    int day = 5, year = 2015;


    const string months[13] = { 0, "January", "February", "March", "April", 
                               "May", "June", "July", "August", "September",
                              "October", "November", "December" };

    cout << months[5] << " " << day << ", " << year << endl;  //the first << is the issue
}

Answer 1

你没有#include <string>，你很幸运，在<string>找到了<iostream>的部分内容，因此你可以声明months。
