I want to use C language and use RSA encryption ,then use base64
encryption ,who has the source code ? give it to me ,thanks very
much .come on !!!! ,I want to use it as soon as possible.thanks again.

It's generally nice, especially with a question like this, to phrase your question politely. In fact, your first and last sentence would have done fine:

Still a poorly researched question, but at least polite. If you googled for "RSA encryption source code", then you'll find the first result says the following:

OpenSSL library is the obvious choice. CryptLib is another option, yet you need to check the license (it's quite specific).

Regarding writing your own code: if you need only RSA, it's not large and you can write it yourself. However, RSA is almost never used by its own. Usually encryption is performed using random key and symmetric algorithm, and then the random key is encrypted with RSA. So if you want data encryption and decide to write your own stuff, you will be reinventing the wheel.
