Comments and Tokens in C
In Programming, Comments are lines of text within code that are meant for human readers rather than the compiler. They serve as explanations, annotations, and guides to the intent behind the code. In C programming, where the lines of code can sometimes appear cryptic, comments act as windows into the programmer’s thought process, illuminating the logic and purpose behind each line.
In the below PDF we discuss about Comments and Tokens in C in detail in simple language, Hope this will help in better understandin
Types of Comments:
Single-Line Comments: These are used for brief annotations or explanations. They begin with // and continue until the end of the line. Single-line comments are great for adding context to specific lines of code.
Multi-Line Comments: Also known as block comments, these are used for longer explanations or for temporarily disabling a block of code. They are enclosed within /* and */ and can span multiple lines.
Benefits of Using Comments
- Code Explanation: Comments elucidate the logic, purpose, and functionality of code. They transform cryptic symbols into readable sentences, making the code’s intent crystal clear.
- Collaboration: Comments foster better teamwork by allowing programmers to communicate their intentions and explanations to fellow developers. This is especially vital in larger projects.
- Code Maintenance: Over time, code can become convoluted. Well-placed comments help developers understand the original purpose, making maintenance and updates easier.
- Debugging: Comments can be used to temporarily disable sections of code for testing purposes. They also serve as signposts during the debugging process.
What is Tokens ?
A Token in C can be defined as the smallest individual element of the C programming language that is meaningful to the compiler. It is the basic component of a C program.
Types of Token
The tokens of C language can be classified into six types based on the functions they are used to perform. The types of C tokens are as follows:
- Special Symbols
A1: Tokens are the fundamental building blocks of C code. They are the smallest individual units that form the structure of a C program, including keywords, identifiers, constants, operators, string literals, and punctuation.
A8: Comments provide explanatory notes within the code, helping programmers and others understand the purpose, logic, and functionality of different parts of the code.
Tokens enhance code readability by providing a clear visual structure. They help programmers understand the logic and flow of the code more easily.
No, comments are ignored by the compiler and have no effect on the program’s execution.
Single-line comments begin with //, while multi-line comments start with /* and end with */.
