# Hey, I'm Malka! 👋

Welcome to **Day 2** of my **#100DaysOfDevelopment** journey. Today, I’m diving into **Variables and Loops in Go (Golang)**.

I'm currently learning from [**Go by Example**](https://gobyexample.com/) — an excellent hands-on resource for beginners!

## 🧠 Understanding Variables in Go

We all know that a **variable** is like a container that stores data. But Go brings its own twist. Here's what I’ve learned so far:

---

### ✅ 1. **Basic Declaration**

Go uses the `var` keyword to declare variables:

```go

var a string

You can also declare multiple variables of the same type on a single line:

var a, b int

---

🧩 2. Type Inference

Go can infer the variable type from the value you assign:

var a = "hello"

Here, you don’t need to mention string — Go automatically figures it out.

\> ⚠️ You must assign a value in this case, otherwise the compiler will throw an error.

---

⚡ 3. Shorthand Declaration

Go provides a short and clean way to declare and initialize variables using :=:

f := "apple"

fmt.Println(f)

No need for var

No need to specify the type

Must initialize at the same time

\> 🔒 This shorthand doesn't work for constants or without initialization.

---

🛑 4. Declaring Variables of Different Types

You can’t do this:

// ❌ Invalid

var a int, b string

But Go allows multiple declarations with inferred types:

// ✅ Valid

var a, b = 10, "Malka"

Or even shorter:

a, b := 10, "Malka"

---

🔐 Constants in Go

Constants are declared using the const keyword:

const a = 7

If a value is provided, Go will infer the type.

Constants cannot be changed after they’re declared.

You cannot use := for constants.

---

🔁 Loops in Go

Go has only one loop keyword — for. But it’s super flexible!

---

🔹 1. Standard For Loop

Similar to C/C++, but Go-style:

for i := 0; i < 5; i++ {

fmt.Println(i)

}

---

🔸 2. While-Like Loop

i := 0

for i <= 10 {

fmt.Println(i)

i++

}

---

🔁 3. Infinite Loop

for {

fmt.Println("I am an infinite loop")

}

To stop it, press Ctrl + C or use a break statement:

for {

fmt.Println("Only once")

break

}

---

🔄 4. Looping a Fixed Number of Times (Using range)

for i := range 3 {

fmt.Println(i)

}

This acts like a loop from 0 to 2 — useful for repeating tasks a fixed number of times.

🔜 What’s Next?

On Day 3, I’ll explore if/else statements in Go — diving into decision-making logic.

I’m also brainstorming some unique beginner-friendly project ideas. I want to go beyond basic calculators or to-do apps and build something useful, creative, and different.

💡 Got a cool idea? Drop it in the comments or send me a DM — I’d love to connect and collaborate!
