This may depend on how much use the variable has though, so you should disassemble if you want to know for sure for some particular recursive function. | |

int a = 5; is in RAM only if declared at global scope. If it's a local variable, it is almost certainly assigned to CPU registers. There are exceptions though: if you take the address of the variable, or if there are not enough available registers, it will end in RAM, but this is uncommon.
