c++ two-dimensional string array counting array number

Two-dimensional string array counts the number of arrays. Is this requirement strange? Not very strange. Some people say that the macro definition of 8 above is not enough. Adding one and subtracting one each time seems to be OK, but it is not boring. I like to use this method. After all, I have the final say in my code.

char xxxxxxxxxxxxName[8][32]{
    "xxx",
    "xxxxx",
    "xxxxxx",
    "x",
    "xx",
    "xxxxxxxxxx",
    "xxxxxxxxxxxx",
    "xxxxxxxxxxxxxx",
};
 int nTotal = sizeof(xxxxxxxxxxxxName) / sizeof(xxxxxxxxxxxxName[0]);

 
 If it is a structure, it is similar. The above is a string array. If it is a structure, just divide it by the size of the structure.
