Study Notes
C Language Introduction
- C is a general-purpose, procedural, and compiled language.
- It was created by Dennis Ritchie in 1972.
- Key features include portability, efficiency, flexibility, and reliability.
- Developed at Bell Labs in 1972.
Basic Syntax Elements
- Variables: Names given to memory locations to store values.
- Data Types: Determine the kind of value a variable can hold (e.g., integers, floating-point numbers, characters).
- Operators: Symbols used for performing operations on variables and values (e.g., addition, subtraction, multiplication).
-
Control Structures: Control the execution flow of a program (e.g.,
if-else, loops,switch).
Data Types in Detail
-
Integer Types: Represent whole numbers (e.g.,
int,short,long,long long). -
Floating-Point Types: Store numbers with decimal points (e.g.,
float,double,long double). -
Character Types: Represent single characters (e.g.,
char). - Arrays: Ordered collections of values of the same data type, stored in consecutive memory locations.
- Structures: Collections of values of potentially different data types, stored contiguously.
Operators Explained
-
Arithmetic Operators: Perform basic mathematical operations (e.g., addition
+, subtraction-, multiplication*, division/, modulo%). -
Comparison Operators: Compare values and return a boolean result (e.g., equal
==, not equal!=, greater than>, less than<).
