I just saw C traps and pitfalls. I saw two definitions and statements. I think it is necessary to understand them. As long as you know, it's just a text game. For example, if you know the differences between the function declaration and the function

OverviewBase64 can convert non-printable encoding into printable encoding for storage.For example, HTTP generally transmits text messages. If you want to transmit images, you must first encode the images into base64 messages for transmission, and
