Thread: Lookup table help

Can you read this kind of way a lookup table or it has to be a multidimensional array mixing the corresponding values one after the other?

Code:

#include <string>
#include <iostream>
using namespace std;

static const char lookup[17] = "0123456789:;<=";

static const char *Hex[] ={
"0x60","0x61","0x62","0x63","0x64",
"0x65","0x66","0x67","0x68","0x69",
"0x71","0x72","0x73","0x74","0x75"
};

int main()
{
    cout << Hex[lookup[13]] << endl;

       return 0;
}
