A circular queue in C solves the main limitation of a linear queue: wasted array slots after dequeuing. In a linear queue, rear keeps advancing rightward; once it hits the end of the array, the queue reports “full” even if dequeued slots at the front are free. A circular queue wraps rear back to index …
A queue program in C implements the FIFO (First In, First Out) data structure — elements are inserted at the rear and removed from the front, just like a real queue. The two core operations are ENQUEUE (insert) and DEQUEUE (remove). This page covers the array-based linear queue with all operations, a step-by-step trace, and …
C Program for Evaluation of Postfix ExpressionIn this program we evaluate the Postfix Expression, using the stack. For example, 456*+7- is the postfix expression, from left one by one it is inserted into the stack, and after evaluation the answer is 27.

Infix to postfix conversion in C transforms a human-readable arithmetic expression like A + B * C into postfix notation A B C * +, where operators follow their operands. Postfix eliminates the need for parentheses and precedence rules during evaluation — a stack scan from left to right is all that’s needed. This page …
Data structures using C, Stack is a data structure in which the objects are arranged in a non linear order. In stack, elements are added or deleted from only one end, i.e. top of the stack. Here we implement the PUSH, POP, DISPLAY stack operations using the array. Read more about C Programming Language . …
An IPv4 address is displayed as four decimal octets separated by dots (e.g., 192.168.1.1) but is stored internally as a single 32-bit unsigned integer. Converting between the dotted-decimal string and the integer form is a fundamental networking operation — inet_addr() in the POSIX socket API does exactly this. Understanding how to do it manually shows …
