如何打印矢量的数据

2021-12-22 00:00:00 visual-c++ c++

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.
