Right declaration of array of pointers to arrays of char *

Question

I want to declare of array of pointers to arrays of char *.

When i compile the code, i got warnings:

warning: initialization of ‘const char *’ from incompatible pointer type ‘const char **’ [-Wincompatible-pointer-types]

This code works, but i know i do something wrong and i should not have any warnings by C compiler. How to declare it right?

const char *S6_ARR[] = {
        "here",
        "we"
};

const char *S7_ARR[] = {
        "go",
        "again"
};

const char *SHEET_HEADER_ARR[] = {
        S6_ARR,
        S7_ARR
};

int main()
{
    ...
}

Learn about typedef. It makes your code much more readable. Take inspiration from existing open source code, e.g. GTK — Basile Starynkevitch

The warning is telling you that you are trying to put elements of type const char ** into an array of type const char *. So change the array type to match what you're putting into it:

const char **SHEET_HEADER_ARR[] = {
        S6_ARR,
        S7_ARR
};
