Inventory Management System In C Language

Here's a simple C Program to develop an Inventory Management System to display the inventory of items in a store. The inventory maintains details such as name, price, quantity & cost. And displays the values in a structured way.<br/><pre class="lang:c decode:true ">// Inventory Management System.<br/>// V 1.0<br/>// MCA Ist Sem, 2015, University of Kashmir.<br/>#include<stdio.h><br/>#include<conio.h><br/>struct item<br/>{<br/> int itemno;<br/> char name[30];<br/> int quantity;<br/> int price;<br/> int tcost;
