Control Flow

Control flow refers to the mechanisms that determine the order in which statements and instructions are executed in a program. In ApLang, control flow structures allow you to make decisions and repeat tasks based on specific conditions, making your code more dynamic and responsive to different situations.

Think of control flow like navigating a city using a map. Just as you might choose different routes based on traffic, weather, or your destination, control flow in programming lets your code choose different paths based on the data it receives and the conditions it encounters.

Control flow includes:

• Making Decisions: Similar to deciding whether to take an umbrella based on the weather forecast, your program can execute certain blocks of code only when specific conditions are met.
• Repeating Tasks: Just as you might wash each dish in a sink full of dirty dishes until they’re all clean, loops in programming allow your program to repeat operations multiple times without having to write the same code repeatedly.
• Branching Execution: This is like choosing a detour if a road is blocked. Your program can direct its execution to different parts of the code based on logical conditions, ensuring it behaves correctly under various circumstances.

In this chapter, we will explore the various control flow structures available in ApLang, including conditionals and loops, which allow you to guide the execution path of your code effectively, just like making decisions and finding the best route on a journey.
