Question

The Names array of char* is located in file1.cpp

char* Names[] = {

    "name1",
    "name2",
    ...
    "nameN"
};

How do I declare it as “extern” in file2.cpp in order to get the values?

Answer 1

You can declare the array of char pointers in file2 as:

extern char*Names[];

A demo in C:

$ cat file1.c
char* Names[] = {"name1","name2","nameN" };

$ cat file2.c
#include <stdio.h>

extern char*Names[];

int  main() {
    printf("%s\n",Names[0]);
}
$ gcc file1.c file2.c && ./a.out
name1
