Loop control variable: A loop control variable is a variable that keeps track of the current position or state in a loop. It is used to control the number of iterations and determine when the loop should terminate.
Outer loop: The outer loop refers to the enclosing loop in a nested loop structure. It determines how many times the inner loop will be executed.
Inner loop: The inner loop refers to the nested or enclosed loop within an outer loop. It executes a specific number of iterations for each iteration of the outer loop.
