Question

Write a program that converts the upper case character in AL to the lowercase but doesn't modify AL if it already contains a lowercase letter. Test your program within different values.

Answer 1

The question asks for a program that converts an uppercase character to its lowercase equivalent but does not alter the character if it's already in lowercase. A Python function called convert_to_lowercase can be used to perform this operation using the isupper() and lower() methods.

Step-by-step explanation:

The student is asking for a computer program that checks if a character (referred to as AL in the question) is in uppercase and converts it to lowercase if it is. However, if the character is already in lowercase, the program should leave it unchanged.

To achieve this, one could write a program in a language like Python, utilizing the built-in functions isupper() and lower(). The following is a sample code snippet that demonstrates this functionality:

def convert_to_lowercase(char):
if char.isupper():
return char.lower()
else:
return char

# Test cases
test_chars = ['A', 'b', 'X', 'y']
for char in test_chars:
print(convert_to_lowercase(char))

This code defines a function convert_to_lowercase that accepts a character as an argument. If the character is uppercase (isupper()), it converts it to lowercase (lower()). Otherwise, it simply returns the character as is.
