C Programming: Convert Character to Lowercase - A Common Error

The code reads a character from the input, converts it to lowercase by adding 32 to its ASCII value, and then prints the character 'A' to the output.

However, the converted character is not printed to the output. Instead, the character 'A' is printed, which is not related to the input character.

To print the converted character, the last line should be changed to:

putchar(A);
