Introduction to Go Programming

Welcome to this beginner-friendly guide to Go programming!
Below, you'll find a series of exercises designed to help you grasp the basics of Go, along with helpful resources and tips.

Installation

To get started with Go, you'll need to install the Go language on your system.
The installation process may vary depending on your operating system. Here is a comprehensive guide to help you through the installation process: Install Go.

Compilation and Execution

  • Once you've written your Go code, you'll need to compile it to run. Here's a quick guide on how to do it:

  • Save your code in a file with a .go extension.

  • Open a terminal or command prompt.

  • Navigate to the directory containing your file.

  • Run go build yourfilename.go to compile your program.

  • Execute the compiled program by running ./yourfilename (on Unix systems) or yourfilename.exe (on Windows).

Exercise 1:

Using a loop, print every number between 1 and 100 !

Exercise 2:

Code a "add" function that adds two numbers together.
This function takes 2 parameters:

  • The number on the left of the '+' operator
  • The number on the right of the '+' operator
add(2, 2) -> 4

You can add any other operation !

Exercise 3:

Write a "countLetter" function to count all letters from a file and print it.
This function take 1 parameter:

  • The file path of your file.
countLetter("myFile")

Exercise 4:

Write a "countWord" function whose objective is to count the number of times a word appears in a sentence.
This function takes 2 parameters:

  • The sentence you will search through.
  • The word you look for in the sentence.
countWord("My cat is playing with my dog!", "my") -> 2

Exercise 5:

Make a simple "isFileSame" function to check if two files have the same content ! This function takes 2 parameters:

  • The path to the first file to check
  • The path to the second file to compare with the first file
isFileSame(firstFile.txt, secondFile.txt) -> false
isFileSame(firstFile.txt, fileWithSameContent.txt) -> true

Exercise 6:

Now, let's make an "appendTofile" function which appends a string to a file !
That function takes 2 parameters:

  • The file you want to append to.
  • The string you want to append to your file.
appendToFile("myFile", "append this") -> if file empty : "append this"
appendToFile("myFile", "append this") -> if file is not empty : "... append this"

Exercise 7:

Now to test all of your functions, make some unit tests !

Final Task: Build a Command-Line Quiz Game

For your final exercise, create a simple command-line quiz game in Go. This project will help you understand user input handling and basic control structures in Go.

Objectives:

Design a Quiz: Create a set of questions (e.g., simple math or general knowledge questions) and store them. Ask Questions: Display each question to the user and ask for their answer. Input Handling: Capture the user's input and check it against the correct answers. Score Tracking: Keep track of the number of correct answers and display the score after the quiz ends.

Tips:

  • Use arrays or slices to store your questions and answers.
  • Explore Go's fmt package for input and output operations.
  • Add a timer feature as an additional challenge, where users have a limited time to answer all questions.

This task will solidify your understanding of Go's syntax and standard library, especially around handling user inputs and simple data structures.
Enjoy coding your quiz game!
