Final answer:
To write a program that reads a word and prints each character on a separate line using a for loop, use a for loop to iterate over each character in the word and print them on separate lines.
Step-by-step explanation:
To write a program that reads a word and prints each character on a separate line using a for loop, you can use the following code in Python:
word = input("Enter a word:")
for char in word:
print(char)
This program prompts the user to enter a word and then iterates over each character in the word using a for loop. It prints each character on a separate line.
