C++ Macro to use values of variables

Question

I have a program with 4 objects of a class, say PO1, PO2, PO3, PO4. I want to call some functions taking these objects as parameters in a for loop. Like so:

for(int i = 0; i < 4; i++){
    func(PO<i>);    //Something like a macro to replace the value i in the function.    

I tried token pasting, but all I got was POi, instead of getting the value of i. Is there any way to do this? (Macro, Function, etc.)

Here's my code

Player PO[4] = {Player{'l',WHITE},
                Player{'l',WHITE},
                Player{'l',WHITE},
                Player{'l',WHITE}
               };

'l' and WHITE are the parameters.

Answer 1

Based on @SamVarshavchik's comment, I got a solution.

Here it is,

Player *PK[4] = {&PO1,&PO2,&PO3,&PO4};
for(int i = 0; i < 4; i++}{
    func(*PK[i]);
}

Answer 2

Use array or std::vector instead

MyObject Pos[4] = {MyObject{42}, MyObject{51}, MyObject{21}, MyObject{12}};

for (auto& po : Pos) {
    func(Po);
}
