Answer Description

A loop structure is used to execute a block of code repeatedly until a certain condition is satisfied. This condition typically involves a counter or the state of data being processed. By understanding loops, programmers can write code that efficiently repeats tasks without manually writing the same lines of code multiple times. For instance, counting from 1 to 10 or iterating through the elements of an array to perform operations on each of them.
