I am having a hard time understanding this program.

I dont understand why this program prints c as 4 instead of 5 on the first cout statement.

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().

Also, I am having a hard time understanding why b and c are both 8 in the second cout statement?
