Using pointers, write a function, rmchr, which takes a string and a character as arguments and removes all occurrences of the character from the string. Print the string both before and after your call to rmchr to demonstrate that the original string was modified. Function rmchr should not produce any output itself. Run your program using the following strings and characters: string character "abracadabra" 'a'

"abracadabra" 'b'

"abracadabra" 'n'

"aaaa" 'a'

"aaaa" 'n'
