C++ Loops

Nested loops, as the name suggests, are loops within loops. They allow you to create more complex and structured patterns of repetition.

To understand this concept better, let's break it down:

• Outer loop: The outer loop is the main loop that controls the flow of your program. It's responsible for repeating the entire process multiple times.
• Inner loop(s): Inside the outer loop, you can have one or more inner loops. These inner loops have their own iteration control and can run multiple times before the outer loop progresses to the next iteration.

To illustrate nested loops, think about the process of marking all the apples inside multiple baskets.

1. Outer Loop (Process of Taking a New Basket with Apples):
   • Begin the process of taking a new basket.
   • For each basket:
     1. Inner Loop (Process for Individual Apples in the Basket):
        • Take an apple from the basket.
        • Mark the apple.
        • Put the marked apple back into the basket.
        • Repeat these steps for every apple in the basket.
   • End the process of taking a new basket.

Nested loops use cases

Nested loops are incredibly useful in a variety of programming scenarios, such as:

• Matrix Manipulation: When working with 2D arrays (matrices), nested loops are essential for accessing and modifying individual elements.
• Pattern Printing: You can create intricate patterns and shapes using nested loops, which is often used in graphical applications or for formatting text.
• Simulations: Many simulations involve multiple layers of repetition. For instance, simulating a game world might require nested loops to handle the time steps and object interactions.
• Data Analysis: In data science and analytics, you might use nested loops to analyze data at multiple levels of granularity.
