Basic of C Programming
Introduction to C Programming: Developed by Dennis Ritchie in 1972 at Bell Labs. Middle-level programming language. Known for its simplicity and efficiency. Widely used for system/software development and embedded systems. Basic Structure of a C Program: c Copy code # include <stdio.h> int main () { // Code goes here return 0 ; } #include <stdio.h> : Inclusion of standard input-output library. int main() { } : Main function, entry point of a C program. Data Types and Variables: Data Types : int : Integer (4 bytes). float : Floating-point number (4 bytes). double : Double-precision floating-point number (8 bytes). char : Character (1 byte). Variables : A name given to a storage area in the program. Example: int age = 25; Operators: Arithmetic Operators : +, -, *, /, % . Relational Operators : ==, !=, <, >, <=, >= . Logical Operators : && (AND), || (OR), ! (NOT) . Control Structures: Conditional Statements : if : Executes a block of co...
