C++ 

Im trying to print the lexeme when the IDENT and INT_LIT tokens are found like the other ones in the picture. 

Could you try helping me print the IDENT and the INT_LIT found?

Im using isalpha for identifiers and isdigit for the integers.

The image contains a series of programming-related tokens that could be part of a script or pseudocode, often used in compiler design or programming language theory. Below is the transcription and a brief explanation: 1. **read KEY_READ** - This likely indicates a read operation, where `KEY_READ` is a keyword for reading input. 2. **IDENT** - `IDENT` stands for identifier, which typically represents a variable or function name. 3. **while KEY_WHILE** - This represents the start of a while loop, with `KEY_WHILE` being the reserved keyword for the loop. 4. **IDENT** - Another identifier, representing a variable or function used within the while loop condition. 5. **<= LEQUAL_OP** - Comparison operation, where `LEQUAL_OP` signifies a "less than or equal to" operator. 6. **INT_LIT** - `INT_LIT` stands for an integer literal, representing a constant integer value. 7. **do KEY_DO** - Indicates the start of a do-while loop block, with `KEY_DO` being the keyword. 8. **{ LEFT_CBRACE** - Denotes the opening of a code block, with `{` indicating the left curly brace. 9. **write KEY_WRITE** - This denotes a write operation, where `KEY_WRITE` is a keyword for outputting data. 10. **IDENT** - Another identifier used in the context of the write operation. 11. **IDENT** - Yet another identifier, potentially acting on or outputting its associated value. 12. **== ASSIGN_OP** - Assignment operation, where `ASSIGN_OP` signifies the assignment (`=`) operator; note: `==` typically signifies equality check. 13. **IDENT** - Identifier potentially being assigned a value. 14. **+ ADD_OP** - Addition operation, with `ADD_OP` indicating the addition (`+`) operator. 15. **INT_LIT** - Another integer literal, representing a constant used in arithmetic operations. 16. **} RIGHT_CBRACE** - Signifies the end of a code block with `}` as the right curly brace. 17. **}** - Close of the outermost block. This script outlines a simple loop structure performing read and write operations with conditional checks and basic arithmetic within a block of code.
