c++ - Take input from keyboard and edit existing text file -

i have been having problems code , lost.
need user use console read text file , update new records.
example doing football type project. have 9 players in football team , want able add new players console, when added start last entry in file , add new 1 there 10 total players if new player added.

void addfootballplayer(football footballplayer[], int *f); {         string forename, surname;     int defence, strike, midfield;     ofstream fout;     fout.open("footballteam.txt");      cout << "enter first name ";     cin >> forename;     cout << endl;     cout << "enter surname ";     cin >> surname;     cout << endl;     cout << "enter strike power  ";     cin >> strike;     cout << "enter defence power  ";     cin >> defence;     cout << "enter midfield power  ";     cin >> midfield; 

you need write file using file stream have defined once have taken inputs , can using fout follows. additionally, there different modes in open file writing it, can go through here.

    fout.open("footballteam.txt");      cout << "enter first name ";     cin >> forename;     fout << forename << " ";     cout << endl;     cout << "enter surname ";     cin >> surname;     fout << surname << " ";     cout << endl;     cout << "enter strike power  ";     cin >> strike;     fout << strike << " ";     cout << "enter defence power  ";     cin >> defence;     fout << defence << " ";     cout << "enter midfield power  ";     cin >> midfield;     fout << midfield << "\n"; 

open , take @ footballteam.txt find above snippet does.

hope helps.
