方式一：

#include 
     
      #include 
      
       void main(){    int m = 4, n = 3;    int **myArray;    myArray = (int**) malloc (m * sizeof(int*));    for(int t = 0; t < m; t++)        myArray[t] = (int*) malloc (n * sizeof(int));    for(int t = 0; t < m; t++)    {        free(myArray[t]);    }      free(myArray);    return;}
