Question 5 Write the code for the function printRoster, it should print out the contacts in a format similar to the example. You can use a range-based for-loop and auto to simplify the solution, if you wish. #include #include #include #include #include using namespace std; void printRoster(map>>& roster) { // Fill code here int main() { map>> roster; roster["ELCO"]["CS-30"]. emplace_back("Anthony Davis"); roster["ElCo"]"cS-30"j. emplace_back("Talen Horton-Tucker"); roster["ElCo"Ï"BUS-101"].emplace_back("LeBron James"); roster["SMC"]["CHEM-101"].emplace_back("Russell Westbrook"); printRoster(roster); return 0; Here is the sample output: ElCo BUS-101: LeBron James CS-30: Anthony Davis Talen Horton-Tucker SMC CHEM-101: Russell Westbrook
