Programming is the act of writing a computer program, and computer programs are written in code. Because of this, many people say "coding" instead of "programming", but they mean the same thing. You'll sound cooler if you say "coding".
Coding is the work of writing instructions that a computer can follow. You can't write code in English or any other human languages—computers aren't smart enough to understand those yet. Instead, you write code in dedicated languages that computers can understand.
Once you know one coding language, it's pretty easy to learn another. This is because almost all programming languages use the same concepts. The words are different, but the structure is basically the same.
