Programming languages can have somewhat strange names. A language named C is a widely-used language, although it is half a century old, and many other programming languages have emerged after the invention of C. The C programming language has influenced many later programming languages.
A famous book named The C Programming Language is written by Brian Kernighan and Dennis Ritchie, the inventors of the language. These authors were the first to introduce a program that prints the text "hello, world" to the screen.
The Internet contains many C language tutorials. The following links might be useful if you want to find more information about C.
