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 …
