Comments in C# Comments are essential for making your code understandable. They can explain what your code does, which is helpful for anyone reading it (including yourself). Inline Comments: Use // for single-line comments. 1 // This is an inline comment. Multi-line Comments: Use /* */ for comments that span multiple lines. 1 2 3 4 /* This is a multi-line comment. It spans multiple lines. */ Semicolons In C#, every statement ends with a semicolon (;). This tells the compiler where a statement ends. ...
