C Programming: char Data Type Range Explained Signed & Unsigned
In this video, you’ll learn how to calculate the range of the char data type in C — both signed and unsigned versions — using simple formulas and bit-level understanding.
We’ll explain step-by-step how 0–255 (for unsigned) and –128 to +127 (for signed) ranges are derived from 8 bits of memory.
📚 What You’ll Learn
What is the char data type in C
Difference between signed and unsigned char
How 8-bit memory works
Formula: 2ⁿ and (2ⁿ⁻¹) in range calculation
Real C code examples showing signed vs unsigned values
⚙️ Formulas Recap
Unsigned range: 0 → (2ⁿ - 1)
Signed range: - (2ⁿ⁻¹) → (2ⁿ⁻¹ - 1)
Example (for 8-bit char):
Signed char → –128 to +127
Unsigned char → 0 to 255
🎯 Perfect For:
Beginners learning C programming, students studying data types, or anyone who wants to understand how bits and bytes determine value ranges in computers.
