The following C language code is required to undergo lexical analysis using clang

Unfortunately, as an AI language model, I am not able to execute or analyze code. However, I can provide you with some general information on how to perform lexical analysis using Clang.

Clang is a C language compiler that can be used to perform lexical analysis on C code. To perform lexical analysis using Clang, you can use the following command in the terminal:

clang -cc1 -dump-tokens <filename>.c

This command will output a list of tokens in the specified C file, which represents the lexical structure of the code. Each token represents a single unit of meaning in the code, such as keywords, identifiers, operators, and literals.

You can also use Clang as a library in your C code to perform lexical analysis programmatically. To do this, you can include the `clang/Lex/Lexer.h` header file and use the `Lexer` class to tokenize the input code. The `Lexer` class provides various methods for reading individual tokens from the input code, such as `Lex`, `getKindName`, and `getLocForEndOfToken`.

Overall, Clang is a powerful tool for performing lexical analysis on C code, and has many capabilities beyond just tokenization.
