Create an algorithm for a program… … that mimics a typical food scale in the supermarket Get the weight of the product (from user input) Get the type of the product (e.g. banana, cucumber, …) (from user input) Price will be calculated based on the weight and the product type The cost will be outputted along with the product type An error is printed when an unknown product number is chosen. An error is printed when the cost will calculate to

#include int main(void) { float weight; int product; printf(„Insert the weight of the product\n> „); scanf("%f", weight); switch (product) { case 0: printf(„Product %d – Banana\n“, valik); hind = 1.28; break; default: hind = 0; break; } cost = price * weight; printf(„Cost: %f“, cost); return 0; } Create a product that would emulate a food scale in a supermarket 5 products (4 of them create by yourself) Show the list of available products to the user User must be able to input the product weight and type Verify that all of the variables needed are declared Create an exception when cost will be 0
