1.Syntax and Structure:
Tokens define the syntax and structure of your C++ code. Each token has a specific role, such as identifying keywords, variables, operators, and punctuation marks. Correct token usage ensures that your code follows the rules of the C++ language.

2.Readability:
Properly formed tokens make your code more readable and understandable. When you use meaningful variable names and follow naming conventions, it’s easier for you and others to comprehend the code’s purpose.

3.Debugging:
Tokens help pinpoint errors in your code. When you encounter a syntax error or a typo, the compiler often reports the line number and token where the error occurred. This information is invaluable for debugging.

4.Code Maintenance:
Well-structured code with consistent token usage is easier to maintain and modify. When you or another developer revisit the codebase, understanding the token structure makes it simpler to make changes without introducing new bugs.

5.Portability:
C++ code that follows proper token usage is more likely to be portable across different platforms and compilers. Non-standard tokens or practices might work on one compiler but not on another.

6.Code Analysis and Tools:
Many code analysis and refactoring tools rely on tokenization to provide suggestions, identify coding standards violations, and improve code quality. Tokens help these tools understand the code’s semantics.

7.Security:
Properly handling tokens can prevent security vulnerabilities such as buffer overflows, injection attacks, and other common security flaws. By validating and sanitizing input, you can ensure that your code interacts safely with external data.
