Defining Structs

In this project, we'll work with collection types such as structs, slices and maps to build a command line application for managing a personal budget. For this module, you will be working on the file named budget_1.go.

By the end of this module, you’ll have defined two structs which will help us organize budget information. ### Solution To view the solution, run git diff origin/master..module1-solution in the Terminal, and press Enter to see the next lines of the difference.

You may also browse the files of the solution by stashing your changes with git stash and running git checkout module1-solution to switch branches.
Challenge

Working with slices and maps

For this module, you will be working on the file named budget_2.go.

By the end of this module, you’ll have defined a series of methods for our existing structs, in combination with slice and map operations, which will help us manage our budget. ### Solution To view the solution, run git diff origin/master..module2-solution in the Terminal, and press Enter to see the next lines of the difference.

You may also browse the files of the solution by stashing your changes with git stash and running git checkout module2-solution to switch branches.
