Question: 1 / 400

What is a nested loop?

A loop executed only once

A loop that does not terminate

A loop within the body of another loop

A nested loop is characterized by having one loop inside the body of another loop. This structure allows for iterative processes to occur at multiple levels, which is particularly useful for working with multi-dimensional data structures like arrays or matrices.

For instance, if you have an outer loop that iterates over rows of a matrix, the nested (inner) loop can iterate over the columns of that particular row. This setup enables complex operations to be performed across all elements of a data structure, facilitating tasks such as searching, sorting, or processing data in a structured manner.

The significance of nested loops lies in their ability to simplify code when handling multi-dimensional data, ultimately making the programming process cleaner and more efficient when executed correctly.
