Write a C++ function named louder which accepts a pointer to a C-string as its argument. It should do 3 things: - change any period (.) in the C-string to an exclamation point (!) - change any lower case letter in the C-string to the corresponding upper case letter - return the number of characters which were changed You may assume that parameter str points to a valid, null-terminated C-string containing only alphabetic characters, spaces and periods. You do not need to demonstrate calling this function. Example: if str points to an array containing "Giants win." the function should change the array so that it contains "GIANTS WIN!", and should return 9.

You may assume that parameter str points to a valid, null-terminated C-string containing only alphabetic characters, spaces and periods. You do not need to demonstrate calling this function.
Example: if str points to an array containing "Giants win." the function should change the array so that it contains "GIANTS WIN!", and should return 9.
You must use this function signature:
int louder(char *str)
