How to delete such kind of two dimension array?

    #define NB -3
    #define NM -2
    #define NS -1
    #define ZO 0
    #define PS 1
    #define PM 2
    #define PB 3


 int (*rule)[7] =new int[7][7]{{NB,NB,NM,NM,NS,ZO,ZO},
                              {NB,NB,NM,NS,NS,ZO,PS},
                              {NM,NM,NM,NS,ZO,PS,PS},
                              {NM,NM,NS,ZO,PS,PM,PM},
                              {NS,NS,ZO,PS,PS,PM,PM},
                              {NS,ZO,PS,PM,PM,PM,PB},
                              {ZO,ZO,PM,PM,PM,PB,PB}};

should I use the following method?

for(int i=0;i<7;++i)
{
   delete[] rule++;
}

Or if I use delete[] rule, it seems weird becuse the underlying object is an array of arrrays, but not array of pointers, which is the type of rule.

rule is an array of pointers to type int[7].

The former was declared with a new[].

Therefore you need to use delete[] rule; to release the memory.
