Exercise 3: Functions in Go

Check Your Go Installation

If you already have Go installed, you can proceed with the exercise. Otherwise, follow this guide to install Go: Install Go

Instructions:

• 1️⃣ Create a file named functions.go in your Go project folder.
• 2️⃣ Declare a function that takes two numbers as arguments and returns their sum.
• 3️⃣ Call the function inside the main() function and print the result using fmt.Println().

🚀 Ready to code? Let's go! 😃

package main

import "fmt"

// Function to add two numbers
func add(a int, b int) int {
    return a + b
}

func main() {
    result := add(5, 3) // Calling the function
    fmt.Println("The sum is:", result) // Displaying the result
}

• 4️⃣ Run the program using the command: go run functions.go

Code Explanation:

1️⃣ func add(a int, b int) int : Declares a function add that takes two integers as input and returns an integer.

2️⃣ return a + b : The function returns the sum of the two provided numbers.

3️⃣ result := add(5, 3) : Calls the add function with arguments 5 and 3 and stores the result in the variable result.

4️⃣ fmt.Println() : Prints the result to the console.
