Answer 1

Explanation:

Here, our task is to replace all the lower-case characters in the string to upper-case and upper-case characters to lower-case. For this purpose, we need to traverse the string and check for each character. If the character is a lower-case character, make it upper-case by using the language-specific built-in method or add 32 to the lower-case character in C to change the ASCII value of the character.
