SUMMARY

The forum discussion revolves around debugging a C++ program that utilizes reinterpret_cast for file operations. The user initially attempts to write integer values to a text file, resulting in unexpected hexadecimal representations instead of the intended character outputs. The discussion highlights that reinterpret_cast is primarily used for converting pointer types and that binary file operations are necessary for non-text data. The user successfully transitions to using binary file mode, demonstrating that mixed data types require careful handling when writing to files.

PREREQUISITES
  • Understanding of C++ data types and pointers
  • Familiarity with file I/O operations in C++
  • Knowledge of binary versus text file formats
  • Experience with debugging techniques in C++
NEXT STEPS
  • Learn about C++ file handling with fstream in binary mode
  • Explore the implications of endianness in binary file operations
  • Study the differences between reinterpret_cast and other casting methods in C++
  • Investigate best practices for handling mixed data types in file storage
USEFUL FOR

Software developers, particularly those working with C++ and file I/O, as well as anyone interested in understanding data type conversions and binary file handling.

...... When the debugger is running, you can evaluate any expression that involves variables that are in scope using the Immediate window.
Debug --> Window --> Immediate
Just type the expression you want to evaluate, and its value will be shown in the window.
I thought you mean to type in the program, now I know type in the Immediate window.

Thanks

If you think about this a minute, it doesn't make any sense. To be using the debugger, you must already have typed in the program. Plus, I said the type the expression you want to evaluate. That doesn't mean "type the program."

Yeh, but ALL the windows opened in debugger were just show what's in it, It's NOT for me to do anything. Don't blame me thinking not to type in the window. I did type in the program and tried. It's not as if I don't read your suggestion.
