C# gets its name from a musical concept. The name "C sharp" was inspired by the musical notation whereby a sharp symbol indicates that the written note should be made a semitone higher in pitch.
In essence, just as a sharp symbol (#) in music raises a note, the C# programming language was conceived as an advancement, or "sharpening," of the C language. Although C# doesn't directly extend C, the name reflects its evolution from earlier languages like C and C++.
