How to define constant 1 or 2 dimensional array in C/C++? I deal with embedded platform (Xilinx EDK), so the resources are limited.
I'd like to write in third-party header file something like
#define MYCONSTANT 5
but for array. Like
#define MYARRAY(index) { 5, 6, 7, 8 }
What is the most common way to do this?
#include <string>
#include <iostream>
#define defStrs new string[4] { "str1","str2","str3","str4" }
using namespace std;
...
const string * strs = defStrs;
string ezpzStr = strs[0] + "test" + strs[1];
cout << ezpzStr << endl;
Took me a while to figure this out, but apparently it works like this in C++. Works on my computer anyway.
Only try to understand what the compiler does. When it finds the HASHTAG , it replaces its content into the place where it's writed. So for example, if u do this:
#define MYARRAY { 5, 6, 7, 8 }
byte list[] = MYARRAY ;
You will get it in the array 'list' . Another way to get the same result is:
#define MYARRAY 5, 6, 7, 8
byte list[] = {MYARRAY} ;
In conclusion, the compliler what does is 'cutting' the hashtag and 'pasting' the content of it. I hope I had solved your doubt
