Greetings! This lesson is instrumental in mastering nested loops in Go. Similar to how our daily routine might involve multiple tasks (inner loops) that we repeat for every day of the week (outer loop), nested loops in programming involve the execution of an inner loop within an outer loop. Let's kick things off!

Suppose your day involves multiple tasks like cooking and eating for each meal: breakfast, lunch, and dinner. In this case, the meals represent the outer loop, while the tasks constitute the inner loop. Similarly, in Go, we can write a for loop (inner loop) inside another for loop (outer loop).

The program evaluates the condition of the outer loop. If it's true, it enters the loop and executes the inner loop to completion before moving on to the next iteration of the outer loop.

Writing nested for loops in Go is straightforward. To demonstrate, let's print a 5x5 star pattern using nested loops:

In this instance, the outer loop governs the rows, while the inner loop controls the columns. The result is a diagonal pattern of stars printed in the console!
