I have the following problem:
#define CONCAT_(A,B) A ## B
#define CONCAT(A,B) CONCAT_(A,B)
#define CREATE_NAME(N) CONCAT(N, __COUNTER__)
If I wanted to retrieve a specific variable##__COUNTER__
later in the code how can I achieve this? I only need to get the previous one, something like:
#define CONCAT_(A,B) A ## B
#define CONCAT(A,B) CONCAT_(A,B)
#define CREATE_NAME(N) CONCAT(N, __COUNTER__)
#define GET_NAME_PREV(N, VAL) CONCAT(N, VAL)
auto CREATE_NAME(v);
auto test_current_counter_value = GET_NAME_PREV(v, __COUNTER__ -1);
Thank you.
