To be clear, what do you mean by "hosting" here? Do you mean some place that provides infrastructure to run your program? If so, what kind of program is it - what does it do?
If not that, do you mean somewhere to keep your code, so others can get it, perhaps work on it or even if you're working by yourself, somewhere to keep the code for backup and version history? The latter is what version control is for, so you can look at Git and creating a repository on GitHub, say.
If neither of these is what you mean by "hosting", please clarify.
