Programming in C++ (Part 7 Structured Data)

This post describes how to use structured data types. Structured data types allow you to group related data together so that it can be passed around easily.

• Simple struct
• Hierarchical structs
• vectors as members of structs
• structs with a vector of objects
• Calculus with structs

Call to Action

Now that you have reviewed the guided code walk-throughs I ask that you write a program that has a struct to represent a cell phone. Every cell phone has a model name and manufacturer along with a camera with a mega-pixel resolution. For example, I may want to store information about an Apple IPhone X with a 12 MP camera or a Google Pixel 4 with a 16 MP camera.

Your program will create three cell phone objects, fill them, and then add them to a vector. Lastly, print out the information about each cell phone on the screen.

Write a function that takes a cell phone object by reference and prompts the user to enter in the model, manufacturer, and camera resolution. Write another function that prints information about a cell phone. Write a function that takes a vector of cell phones and prints each one.
