- This has to be in C++ You want to write a program that will generate accurate shipping charges for a local grocery store. The shipping charges for the store are as follows: Weight of Package (in pounds) Rate per mile Shipped 5 Lbs or less $0.20Over 5 Lbs but no more than 8 Lbs $0.35Over 8 Lbs but not more than 16 Lbs $0.45Over 16 Lbs $0.50 Do NOT use global variables for this exercise. Write a function in a program that asks for the weight of a package in pounds and the distance it is to be shipped. These two arguments are to be passed into the funciton by REFERENCE. Using that data, write a second function (called by the main program) that calculates the shipping charge and returns it to the main program and displays the value inside the main program. For the second function, pass the two values (weight and…arrow_forwardWrite a C program Using structures Which: asks the user to enter the address and the price of a dozen for-sale residential properties in Santa Monica and stores them by their address, price, and type (i.e., condo, single-family home, or land) in an array of structures.

- A phone number, such as (212) 767-8900, can be thought of as having three parts: e.g, the area code (212), the exchange (767), and the number (8900). Write a program that uses a structure to store these three parts of a phone number separately. Call the structure phone. Create two structure variables of type phone. Initialize one, and have the user input a number for the other one. Then display both numbers. The interface might look like this: Enter area code: Enter exchange, Enter number: 415 555 1212 Then display like below: My number is (212) 767-8900 Your number is (415) 555-1212arrow_forwardPlease help with this code and make sure to create in c++. Make sure it is 100% correct and works on Visual studios. Thxs. Write the code as described in the questions below. Submit your code electronically in the box at the bottom. You may only use Java, C# or C++. The economy is defined using a 2-dimensional data structure: A “payday” will be considered to be any region of $ values where all cells in the region are connected either vertically or horizontally. For example, the following illustrates a matrix with 5 rows and 8 columns containing three objects. $’s and P are used in the diagram to represent the two types of values: PPPP$PPPPPP$$PPPPP$$PPP$PP$PPPP$P$PPP$$$ a) Write a program to read in the data from the text file and store it into a data structure.
