C Data Types

C variables have associated data types, defining the stored data (integer, character, float, etc.).
Different data types use varying memory amounts and support specific operations.
Understanding data types is crucial for efficient programming. Online courses exist for deeper study.

Primitive Data Types

Integer

Stores whole numbers (positive, negative, zero).
Supports octal, hexadecimal, and decimal values.
int keyword used for declaration.
Example: int myInteger;

Character

Stores single characters.
Size: 1 byte.
char keyword is used.
Example: char myChar;

Float

Stores floating-point values (decimal, exponential).
Single-precision representation.
float keyword used.
Example: float myFloat;

Double

Stores floating-point values with double precision.
Larger memory capacity than float.
Holds more decimal digits (16-17).
double keyword used.
Example: double myDouble;

Void

Represents no value.
No result value to caller.
Used in function definitions/arguments and pointers.
void keyword used.
Example: void myFunction();

Size and Ranges

Data type size depends on system architecture.
sizeof() operator determines size.
Ranges vary between compilers.
32-bit GCC compiler example ranges, memory, and format specifiers are available but not included here due to extensive data.

This quiz covers the fundamental data types in C programming, including integers, characters, floats, doubles, and the void type. Understanding these data types is essential for effective programming as each type has specific memory usage and operations. Test your knowledge on their definitions and examples!
