Welcome to the C Programming – Complete Course (New Series) by Burle Sharma.
In this class (1.63), we explore all possible formatting cases for printing decimal values using printf() in C.
The following cases are clearly demonstrated with examples:
1️⃣ Only precision mentioned → %.pf
2️⃣ Only width mentioned → %wf
3️⃣ Neither width nor precision → %f
4️⃣ Decimal point only → %.f or %.0f
5️⃣ Left alignment using minus sign → %-w.pf
6️⃣ Width smaller than the printed number → Auto expansion happens
🧮 Practical Program Shown:
Area of Circle program with 2 digits after decimal point
→ Using %0.2f formatting
✨ Bonus Concept Explained Simply:
✔ Single precision (float)
✔ Double precision (double)
✔ General rule:
➡️ If more accuracy required → use double
➡️ Otherwise → float is enough
🎓 What you’ll learn in this video:
✔ All formatting combinations for floating-point output
✔ Difference in accuracy between float and double
✔ Professional formatting for mathematical output
✔ Best practices for choosing float vs double
🧠 Key Learning Point:
Formatted display improves output readability and precision matters in real-life numerical programs.
