Frist b++ is 2 now Frist ans is 2*2=4
NOW it's a increment operator then Frist b++ and ++b it's two times increment that's way b=4
B++ is Frist assign the value again increment this is postinremnt that's way after ans this is 3 and ++b is b=b+1 this is 4
Plz explain this pro
b++ = 3 in 1st condition
++b =4 due to 1st condition
