Question

大家好我尝试打印带有字符的矩阵。我想是这样的：

#include <iostream>
using namespace std;
int main()
{
    char a[3][3]={"a","b","c","d","e","f","g","h","i"};
    int i,j;
    for(i=0;i<3;i++)
        {
            for(j=0;j<3;j++)
            {
            cout<<a[i][j];
            }
        cout<<"\n";
        }
}

我做错了什么？提前谢谢。

Answer 1

你有一个3乘3的int数组。您正在尝试使用字符串文字初始化该数组的每个元素。根本没有从字符串文字（在本例中为const char[2]）的类型到int的隐式转换。

如果您只想要一个字符矩阵，那么请将数组元素设为char。然后你需要使用带单引号的字符文字，而不是字符串文字。

char a[3][3]={'a','b','c','d','e','f','g','h','i'};

Answer 2

你可能想要这个：

char a[3][3]={'a','b','c','d','e','f','g','h','i'};

Answer 3

改变这个：

int a[3][3]={"a","b","c","d","e","f","g","h","i"};

要：

char a[3][3]={{"a","b","c"},{"d","e","f"},{"g","h","i"}};

Answer 4

尝试更改：

int a[3][3]={"a","b","c","d","e","f","g","h","i"};

要：

char a[3][3]={'a','b','c','d','e','f','g','h','i'};

那应该去掉铸造字符到整数。

编辑：将双引号更改为单引号
