I bought my first computer around 1977, a little single-board demonstrator that had to be programmed in binary machine code. In 1979 I bought one of the first Apple IIs. In those days when you bought a computer it came with a book on programming! The language then was BASIC (Beginners All-purpose Symbolic Instruction Code). If you bought a computer in the 1970s, it was because you wanted to learn programming.
Today it's Python. Python is an easy to learn language, made for training, and it's FREE. There are a million tutorials and websites about it online. I think there are whole video courses on YouTube. Or you can buy a book to learn it. (Some of us learn better in a class, some on our own from books and websites.)
When you learn your first computer language, you are learning two things. One is the actual language, but the other is how to program, how to break a problem down and present it to the computer. That understanding of programming, of creating algorithms to make the computer do what you want, is what you are really learning. And that's SOOO much easier to learn with a 'beginner' language. Then go get a book or take a class on C if you want.
Python is actually very powerful for a starter language. It's used in professional programming. So you might never need to learn another language.
