Question

Write a program that asks the user for a positive integer and creates an integer array of that size. the program should then populate all the elements with odd index/subscript with 0 and all the elements with even index/subscript with 1. in the end the program should display the array. you should display a blank space after each array element, as in the sample output below.

Answer 1

The question asks to write a program to create an array with elements set to 0 or 1 based on their even or odd index, respectively, and then display the array.

Step-by-step explanation:

The question involves writing a program that requests a positive integer from the user and then creates an array of that size. In the array, elements with an even index are set to 1, and elements with an odd index are set to 0. Once the array is populated, the program should display the elements of the array separated by a blank space.

Here is an example of how such a program might be written in Python:

size = int(input('Enter a positive integer: '))
array = [0 if i % 2 else 1 for i in range(size)]
for elem in array:
print(elem, end=' ')

This code first takes an input from the user and creates an array of the specified size using a list comprehension, setting the value based on whether the index is odd or even. Finally, it prints out each element of the array.
