Nested loops offer a powerful way to handle complex patterns and relationships within a data structure. By nesting loops, we can break down complex problems into smaller, more manageable tasks. This can greatly improve code organization, readability, and maintainability.
The syntax for creating nested loops is straightforward. It involves placing one loop inside the body of another loop. Here's an example of nested loops using the
In the above code snippet, we have two nested
for loops. The outer loop iterates over the values of
i, while the inner loop iterates over the values of
j. This combination results in a total of 25 iterations, with each iteration printing the current values of
One practical application of nested loops is generating patterns. By carefully manipulating the loop variables and combining them with conditional statements, we can create a wide variety of patterns.
Let's consider a simple example where we want to print a pyramid pattern using asterisks (
*). We can achieve this by using nested loops as follows:
The above code will output the following pattern:
By manipulating the loop variables and the actions performed within the loops, we can create more complex and visually appealing patterns.
Inside the inner loop, add a condition to only log the values of
j if the value of
i is greater than
You should see the following output after running it:
