Go Break and Continue 🎯

Welcome to our deep dive into the fascinating world of Go programming! Today, we're going to explore two powerful control flow statements: break and continue. These statements can help you navigate loops with greater precision and control.

Break 💡

The break statement is used to exit a loop (for, while, or switch) prematurely. By understanding how break works, you can write more efficient and effective code.

Here's a simple example demonstrating the break statement:

package main

import "fmt"

func main() {
    for i := 0; i < 10; i++ {
        if i == 5 {
            fmt.Println("Breaking the loop at 5")
            break
        }
        fmt.Println("Loop Iteration:", i)
    }
}

When you run this code, you'll see output like this:

Loop Iteration: 0
Loop Iteration: 1
Loop Iteration: 2
Loop Iteration: 3
Loop Iteration: 4
Breaking the loop at 5

📝 Note: The loop stops executing once the break statement is encountered.

Continue 💡

The continue statement is used to skip the current iteration of a loop and proceed to the next one. This can be incredibly useful when you want to avoid processing certain iterations based on specific conditions.

Let's examine a simple example of the continue statement:

package main

import "fmt"

func main() {
    for i := 0; i < 10; i++ {
        if i%2 == 0 {
            continue
        }
        fmt.Println("Odd numbers:", i)
    }
}

When you run this code, the output will be:

Odd numbers: 1
Odd numbers: 3
Odd numbers: 5
Odd numbers: 7
Odd numbers: 9

📝 Note: The loop skips even numbers and only processes odd numbers.

Practice Exercise 🎯

Create a program that finds all prime numbers between 1 and 100 using the continue statement.

package main

import "fmt"

func main() {
    // Your code here 📝
}
