C Programming – Standard Input/Output (Part 2)
Formatting, Precision, Memory Analysis & Debugging in Eclipse
Welcome to PicoBit-Tech.
I’m Behnam Jafari, and in this session we continue our deep dive into Standard Input and Output functions in C — an essential foundation for microcontroller programming and embedded systems development.
This video is Part 2 of our series on mastering formatted input/output in C.
📌 Timestamps
00:00 – Introduction
01:15 – Exercise 1: Examining Memory for a String Variable
05:54 – Exercise 2: Using Flags for Formatting
07:58 – Exercise 3: Aligning Strings on a Single Line

🖥 What You Will Learn
🔹 Exercise 1 – Memory Examination
Understand how string variables are stored in memory and how to inspect their behavior during execution.
🔹 Exercise 2 – Formatting with Flags
Learn how to use formatting flags in printf() to control output appearance and structure.
🔹 Exercise 3 – String Alignment
Align strings properly within formatted output to create structured and readable console displays.
🔹 Exercise 4 – Using Precision
Explore the .precision specifier for:
-
Controlling string output length
-
Managing floating-point number formatting
🐞 Debugging in Eclipse IDE
We also cover practical debugging techniques inside Eclipse IDE, including:
-
Monitoring variable values
-
Tracking memory changes
-
Using external consoles for improved output visibility
To enable debugging support, you may need the GNU Debugger (GDB):
🔗 GDB Package (MSYS2):
https://packages.msys2.org/packages/mingw-w64-x86_64-gdb
🎯 Why This Lesson Is Important
By the end of this tutorial, you will:
✔ Use printf() professionally with flags, alignment, and precision
✔ Understand how strings are handled in memory
✔ Improve debugging skills for C programming
✔ Strengthen your foundation for embedded and microcontroller development
If you haven’t watched Part 1 yet, we recommend starting there to build a complete understanding of standard I/O concepts in C.
