Final answer:

To print a rectangle using nested loops, create an outer loop for the rows and an inner loop for the columns, using print statements to generate the desired pattern.

Step-by-step explanation:

The question seems to be asking how to write nested loops in a programming language to print a rectangle, where the number of rows and columns are specified. Nested loops are used in programming to perform repeated operations—such as printing multiple rows and columns, which is typical when outputting a rectangular pattern.

Example in Python:

rows = 5
columns = 4
for i in range(rows):
for j in range(columns):
print('*', end=' ')
print('')

This code will produce a rectangle of asterisks (*) with 5 rows and 4 columns. The outer loop runs once for each row, and the inner loop runs once for each column in a single row. The print function in the inner loop prints an asterisk followed by a space without moving to the next line (end=' '), and the print function in the outer loop moves the cursor to the next line to start printing the next row.

Final answer:

The student's question involves writing nested loops to print a rectangle in a programming language. An example was provided using Python, demonstrating how to use an outer loop for rows and an inner loop for columns to print a rectangle of a specific size.

Step-by-step explanation:

The student is asking how to write nested loops to print a rectangle given the number of rows and columns. In most programming languages, you can achieve this by using a loop inside another loop. The outer loop will run for the number of rows, and the inner loop will run for the number of columns. Here's a simple example in Python:

rows = 3
columns = 2
for i in range(rows):
for j in range(columns):
print('*', end=' ')
print()

This will output a rectangle that is 3 rows high and 2 columns wide, filled with asterisks ('*').

Understanding nested loops is a key concept in programming, as they allow the execution of a set of statements multiple times. These loops are extremely useful for handling multidimensional data structures like matrices, grids, and more complex computations that involve repeated actions within different layers of iteration.
