C++程序设计 搭建项目框架

编写一个程序，将 “粤, 港, 澳, 大, 湾, 区” 这6个字存入一个2行3列的二维数组，再按下图的格式输出，最后将该数组的内容存入txt文件。

下图的格式，汉字之间多少空格啊

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
    string str[2][3] = {"粤","港","澳","大","湾","区"};
    for(int i=0;i<2;i++)
    {
        for(int j=0;j<3;j++)
            cout<<str[i][j]<<" ";
        cout<<endl;
    }
    fstream out;
    out.open("D:\\yga.txt", ios::out);  // write,清空再写入
    
    for(int i=0;i<2;i++)
    {
        for(int j=0;j<3;j++)
            out.write(str[i][j].c_str(),str[i][j].length());
    }
    cout<<"数组存盘成功!"<<endl;
    out.close();
    return 0;
}

#include <stdio.h>

int main()
{
    char buf[][4] = {"粤","港","澳","大","湾","区"};
    //2行3列输出
    for(int i=0; i<6; i++) {
        printf("%s", buf[i]);
        if((i + 1) % 3 == 0) //一行3个元素
            printf("\n");
        else
            printf("\t");
    }
    //存入txt文件
    FILE *fp = fopen("D:\\1.txt", "w");
    if(fp == NULL) {
        perror("open failed");
        return -1;
    }
    for(int i=0; i<6; i++) {
        fprintf(fp, "%s", buf[i]);
        if((i + 1) % 3 == 0) //一行3个元素
            fprintf(fp, "\n");
        else
            fprintf(fp, "\t");
    }
    fclose(fp);
    printf("数组存盘成功\n");

    return 0;
}

#include <stdio.h>
#include <stdlib.h>
#include <locale.h>
int main() {
 setlocale(LC_ALL,"chs");
 wchar_t a[2][3]={{L'粤',L'港',L'澳'},{{L'大',L'湾',L'区'}};
 for (int y=0;y<2;y++) {
  for (int x=0;x<3;x++) {
   wprintf(L"%c    ",a[y][x]);
  }
  wprintf(L"\n");
 }
 FILE *f=fopen("a.txt","wb");
 fwrite((const void *)&a[0][0],sizeof(wchar_t),6,f);
 fclose(f);
 wprintf(L"数组存盘成功！\n");
 system("pause");
 return 0;
