                问题描述

                我在互联网上搜索了很多,但找不到打印矢量数据的简单示例..

                I've searched a lot over the internet, and couldent find simple examples to print vector's data..

                我试图像数组一样打印它,但它没有用...

                I tried to print it like an array, though it didnt worked...

                这是我尝试过的:

                using namespace std ;
                .....
                const int MAX = 255 ;
                
                vector <string> testersName[MAX];
                cout << testersName[i] << endl;
                

                错误仅在 cout 行中,第一行正在得到遵守,一切顺利..

                The error is only in the cout line, the first line is getting complied and everything goes well..

                我在 testersName 中得到了数据,但我收到了这个错误:

                I got data inside testersName, though Im getting this error :

                "错误 1 错误 C2679: 二进制 '<<': 没有找到使用std::vector<_Ty>"类型的右侧操作数的运算符(或者没有可接受的转换)"

                "Error 1 error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'std::vector<_Ty>' (or there is no acceptable conversion)"

                推荐答案

                vector testersName[MAX]; 声明了一个向量数组,尝试简单的 vector ;testersName(MAX); - 这声明了一个带有 MAX 元素的向量.

                vector <string> testersName[MAX]; declares an array of vectors, try simply vector <string> testersName(MAX); - this declares a vector with MAX elements.
