Question

What are the two types of comments?

Answer 1

In programming, the two main types of comments are:

1. Single-line comments:
   

   - These comments are used to add brief explanations or notes on a single line of code.
   - They begin with a special character or sequence, depending on the programming language.
   - Example in C++ or Python:
     `python
     # This is a single-line comment
     `

1. Multi-line comments:
   

   - These comments span multiple lines, making them useful for longer explanations or temporarily disabling blocks of code.
   - In some languages like C++, Java, or JavaScript, they are enclosed within / and /.
   - Example in C++ or Java:
     `java
     /* This is a multi-line comment
        It spans across several lines */
     `

   - In Python, you can use triple quotes (''' or """) for multi-line comments:
     `python
     '''
     This is a multi-line comment
     that goes across multiple lines
     '''
     `

These comments are ignored by the compiler or interpreter and don't affect the execution of the code. They are only meant for humans reading the code to understand it better.
