Does Section 375 And 376 Same? Date Rape Comes Under Which Section?

Can the victim give consent under intoxication? (With her consent, when, at the time of giving such consent, by reason of unsoundness of mind or intoxication or the administration by him personally or through another of any stupe­fying or unwholesome substance, she is unable to understand the nature and consequences of that to which she gives consent.) The guy promised marriage, intoxicated and slept, again promised wedding and later broke the wedding plan. So if the victim lodges an FIR, they booked it under 376. What is 375 ? Are both same and will the victim claim anything? They are saying that the victim gave consent so it is false rape. The accused is in jail. What are the possibilities?
