Assign each track runner a roster number and calculate the average age of the team. As output the program should print the roster in three columns like in the following format: Roster # Name Age 1 First Name 18 2 Second Name 19 3 Third Name 19 4 Fourth Name 20 5 Fifth Name 18 The average age of the team is 18.80.

Your source code must make use of the following A looping structure (for, do-while, while) A struct Use string data type for text variables Validate user input and ask for corrections if invalid input detected Use formatted output for the team roster

// includes struct People{ string new_name; double new_age; }; bool check_name(string name){ /* bla bla Just check name - return true if incorrect, false if is ok. */ } int main() { vector < People > vec; string name; double age, sum=0; int N; do{ cin.clear(); cin.sync(); cout << "How many people?: "; cin >> N; while(!cin.good() || N <= 0); while(N-- > 0){ cout << "Enter your name: "; getline(cin, name); cout << "Enter your age: "; cin >> age; if(!cin.good() || check_name() || age <= 0){ cin.clear(); cin.sync(); N++; }else{ People *p = new People; p->new_name = name; p->new_age = age; vec.push_back(p); delete p; }} cout << "Roaster #\t\tName\t\tAge" << endl; for(int i = 0; i < vec.size(); i++){ cout << i+1 << "\t\t" << vec[i].new_name << "\t\t" << vec[i].new_age << endl; sum+=vec[i].new_age; } cout << "The average age of the team is" << sum/vec.size() << endl; return 0; } Try it.
