myTable = {1, 2, 3}

A Lua "table" is just a generic associative mapping, which maps a set of keys to a set of values. In this special case it also happens to be what is known as a list or array in most programming languages. Read up on datastructures and you should find that C++ also has a notion of arrays, lists, mappings, ...

If you need a fixed size array you can do:

int array[] = {1, 2, 3};

If you need a dynamic array, one that can change in size, use std::vector:

std::vector<int> vector = {1, 2, 3};

@Mussi, :( I tried the std::vector but it gave me this error:

C:\Games\SFML Games\Test\main.cpp||In function 'int main()':|
C:\Games\SFML Games\Test\main.cpp|17|error: in C++98 'a' must be initialized by constructor, not by '{...}'|

||=== Build failed: 2 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

The code I tried was:

std::vector<int> a = {1, 2, 3};

std::vector<int> numbers = { 1, 2, 3 };

int numbers2[3] = { 1,2,3 };

std::map<std::string,std::string> fruits;
fruits["apple"] = "red";

Did you remeber to #include ?

He is probably not using C++11.

Did you remeber to #include <vector> ?
Also what compiler and version are you using, it looks like it doesn't support c++11 initializer lists...

Ofcourse I didn't forget to #include <vector>, compiler:

I'm also using Code::Blocks.

Btw, how can I use C++11 ?

He is probably not using C++11.

The error message implies that he is compiling in C++98 mode using a compiler that also supports later versions, probably gcc

passing -std=c++11 to the compiler should fix that, in code::blocks there should be a checkbox under settings>compiler>compiler flags that he can check.
