In this project products can be added with their name, price and quantity. We can also modify the product’s name, price and quantity can be modified. Also we can delete and search the products available in the stock. So we can easily access the records of the products using this project. This project will also help the owners of the electronic equipment shops to carry out the day to day business in a smooth and organised way. Also, it saves a lot of time of the owners. Using this project adding, updating and deletion of records can be done which results in proper resource management of stock data.
In this project, linked list is used as the main data structure to add the products which will store the products in the memory. As we are using linked list so firstly a structure data type is defined in which product’s name and price are declared using one-dimensional array and the pointer pointing to the next node of the list is also declared which is of the same struct data type. Here, memory is allocated dynamically using malloc() function where the product’s information is stored.
LINKED LISTS:
Linked list is a collection or sequence of nodes where each nodes has two parts. One part is for information and the other part is for pointer. Here the link pointer points to the next node present in the list.Linked lists are similar to arrays as both are linear data structure. The main difference is that the arrays elements are stored in contiguous memory locations and in linked lists, elements are stored in non contiguous memory locations. Also, in linked lists memory is not fixed, we can keep adding and removing elements without any capacity constraints.
ARRAYS:
An array is a collection of similar type of data items and each data item is called an element of the array. The elements of array share the same variable name but each element has a different index number known as subscript. In C, the subscripts starts from 0. Arrays can be single dimensional or multidimensional. The number of subscript determines the dimension of an array. Also, array is a linear data structure. In this project 1-D arrays are used.
To deploy this project run it on any of the following softwares :-
CODE BLOCKS (IDE), TURBO C/C++ , VISUAL STUDIO CODE (IDE) , COMPILER LIKE MINGW DEV C++ .
