Solution
The pseudocode provided describes a program that prints the characters of a string in reverse order. Here's a step-by-step breakdown:
- An array variable called 'word' is declared. This will hold the string that will be reversed.
- A counter is declared. This will be used to iterate through the 'word' array.
- A string is stored in the 'word' array. This is the string that will be reversed.
- A FOR loop is initiated. The loop starts at the last index of the 'word' array (which is the length of the word minus one) and ends at the first index (0).
- Inside the loop, the counter is decremented by one each time. This means that the loop will go through the 'word' array from the end to the beginning.
- The character at the current index of the 'word' array (which is the current value of the counter) is printed.
- The loop continues until it has gone through all the indices of the 'word' array, effectively printing all the characters of the string in reverse order.
So, the multiple choice options could be:
A) The pseudocode prints the characters of a string in the order they are stored. B) The pseudocode prints the characters of a string in reverse order. C) The pseudocode counts the number of characters in a string. D) The pseudocode replaces each character in a string with the next one in the alphabet.
The correct answer would be B) The pseudocode prints the characters of a string in reverse order.
