1. A grocery shop owner wants to store the information about the products that he has in the stock. A product has its unique id, name, brand name, type (for example food, cosmetic, electronic etc.), quantity and price of each unit. First you have to design a structure with appropriate entry according to the problem specification. You should have come up with something like this: struct product { int id; string name; }; a. Now create an array of the defined structure and let the user to decide how many products info he/she wants to store. Then store the information using the created array of structure. After that display the name of the products and their prices whose prices are greater than 40. b. Repeat the process of (a) using dynamic memory allocation. First, declare a product type pointer variable and allocate needed memory dynamically for the requirement of the user. Suppose user wants to store information about n product. product *ptr; ptr = new product[n*sizeof(product)]; Now loop through n and take the user inputs. For taking input you can use this (->) pointer. This is also applicable for displaying and accessing data of the structure.
