编写函数，返回一个二维的字符数组

下面是我写的代码：

#include<stdio.h>
#include<stdlib.h>
#define COL_SIZE 4
#define RAW_SIZE 4
char ** get()
{
  char ** charPoint2 = (char **)malloc(sizeof(char*)*COL_SIZE);
  int i = 0;
  for(i = 0; i < RAW_SIZE; i++)
  {
    *(charPoint2 + i) = (char *)malloc(sizeof(char)*COL_SIZE);
  }
  int j = 0;
  for(i = 0; i < RAW_SIZE; i++)
    for(j = 0; j < COL_SIZE; j++)
    {
      *(*(charPoint2 + i) + j) = (char)(i + j + 70);
    }
  return charPoint2;
}
int main()
{
  char ** charPoint2 = get();
  int i,j;
  for(i = 0; i < RAW_SIZE; i++)
    for(j = 0; j < COL_SIZE; j++)
    {
      putchar(*(*(charPoint2 + i) + j));
      putchar(' ');
      if (j == 3)
      {
        printf("\n");
      }
    }
  return 0;
}

下面是输出的结果：

F G H I 
G H I J 
H I J K 
I J K L
