感谢@crashmstr触发右脑细胞正常工作。我的问题是您不能将具有该格式的整数写入数组。
cin >>票[a] [0];是解决问题的正确答案。
#include<iostream>
#include<iomanip>
#include<istream>
#include<string>
using namespace std;
const int nameRow = 6, nameCol = 7, voteRow = 6, voteCol = 2;
int main ( )
{
char candName[nameRow][nameCol];
int votes[voteRow][voteCol];
for(int a=0;a< nameRow;a++)
for (int b = 0; b < nameCol;b++)
candName[a][b] = 0;
for (int c = 0; c < voteRow;c++)
for (int d = 0; d < voteCol;d++)
votes[c][d] = 0;
cout << "Enter a candidate's name : ";
for (int a = 0;a < nameRow;a++)
{
cin >> candName[a], nameCol;
cin >> votes[a], voteCol;
}
system ( "pause" );
}
我的问题是文件的最后一个cin。 >>正在获取代码。我把它放在同一行，另一个循环，相同功能的不同循环或不同功能的所有行的>>跳闸C2679都没关系。
我看到的最流行的修复方法是使用#include<string.h>，并将其更改为<string>。最初我没有它，但是看到它时就添加了它，但是它并没有解决任何问题。
谁能给我一些我所缺少的见识？
错误消息：
binary '>>' : no operator found which takes a right-hand operand of type 'int[2]' (or there is no acceptable conversion)

使用#include <string>是解决方案的一部分，但是您忘记了实际使用字符串类型。另外，您还会使用很多古董。代码如下：
#include<iostream>
#include<iomanip>
#include<string>
const int numRows = 6;
int main ( )
{
std::string candName[numRows]; // empty strings
int votes[numRows] {}; // zero-initialized
for (int a = 0;a < numRows;a++)
{
std::cout << "Enter a candidate's name : ";
std::cin >> candName[a] >> votes[a];
if ( ! std::cin )
break; // stop if they type something bad
}
}
另一个容易进行的修改是将结果存储在用户定义类型的vector中，该类型包含string和int，而不是具有两个固定大小的数组。然后，您可以接受任意数量的输入，而不仅仅是6个。

替换为,或类似的内容：
>>这是一个非常糟糕的风格：
for (int a = 0;a < nameRow;a++)
{
cin >> candName[a], nameCol; // << -- here
cin >> votes[a], voteCol; // << -- and here
}
请添加这样的大括号：
for (int c = 0; c < voteRow;c++)
for (int d = 0; d < voteCol;d++)
votes[c][d] = 0;
答案 2 :(得分：-2)
在标准输入流中，您只能采用一个由空格分隔的输入。
因此，不像二维数组的cin >> candName[a], nameCol;那样支持从标准输入流中进行for循环读取。
可能您想做这样的事情。
cout << "Enter a candidate's name : ";
for (int a = 0; a < nameRow; a++) {
for (int b = 0; b < nameCol;b++) {
cin >> candName[a][b];
}
}
