In function DisplayRank(), if rankPointer is null, print "rankPointer is null.". Otherwise, print the value in the variable pointed to by rankPointer. End with a newline.

Ex: If the input is Y D, then the output is:

#include <iostream>
using namespace std;

void DisplayRank(char* rankPointer) {

/* Your code goes here */

}

int main() {
char rank;
char* rankPointer;
char action;

rank = '0';
cin >> action;
cin >> rank;

if (action == 'Y') {
rankPointer = &rank;
}
else {
rankPointer = nullptr;
}

DisplayRank(rankPointer);
