For didactic reasons, we don't do students homework on the forum. They learn much more when doing it themselves.
So let me only ask: what's your problem?
1. Don't you know or understand that decimal 105 is binary 1101001 and hexadecimal 69?
2. Do you understand how to read it, but can't design (the details of) the algorithm to calculate it?
3. Do you understand the necessary algorithm (= can you do on paper) but are you having troubles translating it to C++?
That are 3 totally different problems that need totally different help. So even if we would like to help, we couldn't do it with the information you provide.
Best of luck with your study!
