Write a program that displays the pattern show in the * sample executable. * * Type of loop-> your favorite (you must use a pair of * nested loops) * Hints: * 1) Use variables that increments * 2) When running the sample, use values between 61 and * 76 for the number of columns, values between 16 and * 21 the number of rows * 3) Start with a rectangular array of "X" then figure out * how to create one of the upward lines and then the * backwards lines and then both lines

Answer 1

The program example provided demonstrates how to create a pattern with diagonal lines using nested loops in Python, based on user input for the dimensions of the pattern.

Step-by-step explanation:

To create a pattern using nested loops in a programming language, you can start with a rectangular array of 'X' and then modify the output using conditions to create diagonals. Here's an example of a Python program that does this:

num_cols = int(input('Enter the number of columns (61-76): ')) num_rows = int(input('Enter the number of rows (16-21): ')) for row in range(num_rows): for col in range(num_cols): if row == col: print('/', end='') elif col == num_cols - row - 1: print('\\', end='') else: print('X', end='') print()

This program uses two nested loops. The outer loop iterates through each row, while the inner loop iterates through each column within that row. At each position, it decides whether to print 'X', a forward-slash '/', or a backslash '\\', creating a pattern with diagonal lines crossing an array of 'X's.

The program prompts the user to enter the desired dimensions for the pattern and validates that they're within the suggested ranges. Remember to choose values for num_cols and num_rows according to the specifications provided in the instructions (between 61-76 for columns and between 16-21 for rows).
