#include <stdio.h>
#include <iostream>

using namespace std;

//char* b[6] = new char[6];

char a[6] = {'b','c','d','e','f','g'};
char c[6] = {'a','b','d','d','f','g'};

int main()
{
    char d[][6]={*a,*c};



    for (int x = 0 ; x < 1; x++)
    {
        for(int y = 0; y<6; y++)
        {
            char test = d[x][y];
            cout << test <<"\n";
        }
    }
    return 0;
}

此代码是 C++ 代码。我正在尝试创建一个存储 char 数组的类。然后还有另一个 char 数组，该数组存储已声明的 char 变量。它编译得很好，但它并没有达到应有的效果。当程序尝试打印值时，它没有给我正确的值

可能你的意思是指针数组：

char *d[]={a,c};

我从这个问题中了解到，您想要创建类来存储已经初始化的 char 数组。

#include <stdio.h>
#include <iostream>

    char a[6] = {'b','c','d','e','f','g'};  // Initialized character array. MAX 6

    // This class will hold char array
    class Test {    
    public:
        void setName(char *name);
        const char* getName();
    private:
        char m_name[6]; // MAX 6 ( since you already initialized(MAX 6), So no need dynamic memory allocation. )
    };

    void Test::setName(char *name) {
        strcpy(m_name, name); // Copy, already initialized array
    }

    const char* Test::getName() {
        return m_name;
    }

   int main(int argc, char** argv) {
    {
        Test foobar;       
        foobar.setName( a );  // set the pointer which point to starting of the initialized array.
        cout << foobar.getName();
        return 0;
    }
