C Language – Inventory & Versions 🌟 C Language – Inventory & Versions This page covers the history, versions, syntax, data types, variables, constants, and operators in C with examples. 1. Inventory (History & Origin) Year Event 1969–1972 Developed by Dennis Ritchie at Bell Labs as a system programming language for UNIX. 1978 K&R C (first edition of The C Programming Language book published). 1989 ANSI C (C89) standard approved by ANSI. 1990 ISO C (C90) standardized internationally. 1999 C99 update introduced inline functions, variable-length arrays, // comments, and more. 2011 C11 introduced multi-threading support, Unicode handling, bounds-checking functions. 2018 C18 (minor revision of C11) — bug fixes and clarifications. 2. Why Use C? Foundation of programming – base for languages like C++, Java, C#. System-level programming – OS, compilers,...

Operators and expressions

-
Operators and Expressions in C In C language, operators are special symbols used to perform operations on data and variables. An expression is a combination of operators and operands (variables/constants) that produces a result. Example: a + b is an expression where + is an operator and a , b are operands. 1. Arithmetic Operators These operators are used for mathematical calculations like addition, subtraction, multiplication, etc. Operators: + (Addition), - (Subtraction), * (Multiplication), / (Division), % (Modulus) #include <stdio.h> int main() {   int a = 10, b = 3;   printf("a+b = %d\\n", a+b);   printf("a-b = %d\\n", a-b);   printf("a*b = %d\\n", a*b);   printf("a/b = %d\\n", a/b);   printf("a%%b = %d\\n", a%b);   return 0; } Output: a+b = 13 a-b = 7 a*b = 30 a/b = 3 a%b = 1 2. Relational Operators These operators are used to co...

Looping statements in c

Looping Statements in C 🔁 Looping Statements in C Loops allow repeating code multiple times until a condition is satisfied. 1️⃣ for Loop 📘 Full Definition The for loop is used when the number of iterations is known in advance. It combines initialization, condition, and increment/decrement in a single line. ⚡ Shortcut: Best for fixed repetitions. 🔹 Syntax: for(initialization; condition; update) { // code to execute } Show Example #include <stdio.h> int main() { for (int i = 1; i 2️⃣ while Loop 📘 Full Definition The while loop is used when the number of iterations is not known in advance. It keeps executing as long as the condition is true. ⚡ Shortcut: Repeat while condition is true. 🔹 Syntax: while(condition) { // code to execute } ...
