Question: I am having a hard time understanding this program. I dont understand why this program prints c as 4 instead of 5 on the line

I am having a hard time understanding this program.

I dont understand why this program prints c as 4 instead of 5 on the line commented in the code.

I know a is 1 and b is 2 because when the recursion call ends those variable goes away.

A remains 1 because of the global variable, and b remains 2 due to the local B in main().
