Nested For Loop

Definition

A nested for loop is a loop structure where one loop is placed inside another loop. It allows for the repetition of a set of instructions within another set of instructions, resulting in more complex and controlled iterations.

Analogy

Imagine you are organizing a school event with multiple activities happening simultaneously. Each activity has its own schedule (inner loop), but all the activities are part of the overall event schedule (outer loop). The nested for loop helps you manage and coordinate all the different activities efficiently.

Related terms

Outer Loop: The outer loop refers to the enclosing or higher-level loop in a nested for loop structure. It controls the execution of the inner loops and determines how many times they will be repeated.

Inner Loop: The inner loop refers to the enclosed or lower-level loop in a nested for loop structure. It executes its set of instructions repeatedly as long as its conditions are met, within each iteration of the outer loop.

Control Flow: Control flow refers to the order in which statements and instructions are executed in a program. In nested for loops, control flow moves from one iteration of an outer loop to all iterations of an inner loop before returning to the next iteration of the outer loop.
