Introduction to Tokenization Process in Lexical Analysis

🔍 Tokenization is the process of counting the number of tokens in a given code segment.

🔢 Tokens can be classified into seven categories: identifiers, operators, constants, keywords, literals, punctuators, and special characters.

⚙️ In the provided source code, the first token encountered is the keyword 'end', followed by the identifier 'main'.

🔑 The video discusses tokenization in lexical analysis, which involves categorizing different elements of a code into tokens.

🧩 Tokens can be categorized into punctuators, keywords, identifiers, and operators.

🔢 The example code mentioned in the transcription demonstrates the process of tokenization by incrementing a count for each encountered token.

⚡ The lexical analyzer scans the source code line by line, counting each token it encounters.

🔤 Identifiers and fixed values are categorized as tokens and increase the token count.

➕ Punctuators, like the comma, also increase the token count when encountered.

🔑 There are 27 tokens in the given code.

✍️ Identifiers, operators, and punctuators are the main token categories.

🔢 The count of tokens increases as we encounter identifiers, operators, and punctuators in the code.

🔍 The video explains how to tokenize a program using a lexical analyzer.

✏️ The process involves identifying different tokens in the program, such as identifiers, literals, and punctuators.

📈 The token count increases as each token is encountered and categorized.

💡 The video explains the concept of tokenization in the lexical analysis process.

🔑 Tokens are identified based on different types such as punctuators, keywords, identifiers, and constants.

🔢 The example code in the video contains 39 tokens.

↑ The video introduces the concept of a Lexical Analyzer and its role in counting tokens in a code segment.

→ Tokens include punctuators, operators, constants, and string literals, and the Lexical Analyzer counts every occurrence of tokens.

✔ In the next session, numerical problems related to the Lexical Analyzer will be solved.
