次に、低関数の順序に一致するログファイルを比較して作成します.

std::cout << "amount:" << _amount << ";";
std::cout << "created" << std::endl;
Account::_nbAccounts++;
Account::_totalAmount += _amount;
}void Account::displayAccountsInfos()
{

std::cout << " accounts:" << Account::_nbAccounts << ";";
std::cout << "total:" << Account::_totalAmount << ";";
std::cout << "deposits:" << Account::_totalNbDeposits << ";";
std::cout << "withdrawals:" << Account::_totalNbWithdrawals << std::endl;
}Account.cppがあり、中間統計の感覚で出力される内容です.うん.吸気剤で近づけるように言われたようですが、忘れてしまいました..^^!void Account::makeDeposit( int deposit )
{
int p_amount;
p_amount = _amount;
_amount += deposit;
_nbDeposits++;
_displayTimestamp();
std::cout << " index:" << _accountIndex << ";";
std::cout << "p_amount:" << p_amount << ";";
std::cout << "deposits:" << deposit << ";";
std::cout << "amount:" << _amount << ";";
std::cout << "nb_deposits:" << _nbDeposits << std::endl;
Account::_totalNbDeposits++;
Account::_totalAmount += deposit;
}[20220103_011945] accounts:8;total:20049;deposits:0;withdrawals:0の価格上昇に伴い、depositの価格が変動した.amountと理解した後、関数を作成するための新しいパラメータ인덱스; 금액; 예치금; 금액 + 예치금; 예치금 횟수;が発表された.p_amountで使用するために、displayAccountsInfosパラメータ値が与えられる.bool Account::makeWithdrawal( int withdrawal )
{
int p_amount;
p_amount = _amount;
_amount = _amount - withdrawal;
_displayTimestamp();
std::cout << " index:" << _accountIndex << ";";
std::cout << "p_amount:" << p_amount << ";";
if (_amount >= 0)
{
_nbWithdrawals++;
std::cout << "withdrawal:" << withdrawal << ";";
std::cout << "amount:" << _amount << ";";
std::cout << "nb_withdrawals:" << _nbWithdrawals << std::endl;
_totalNbWithdrawals++;
Account::_totalAmount -= withdrawal;
return (true);
}
else
{
std::cout << "withdrawal:refused" << ";" << std::endl;
_amount = p_amount;
return (false);
}
}total関数が인덱스; 원금; 회수액; 원금 - 회수액; 회수 횟수;boolenが원금 - 회수액より大きいと宣言した場合、小さな出力文も異なるため、条件文は各戻り値を0とtrueに分けます.Account::~Account()
{
_displayTimestamp();
std::cout << " index:" << _accountIndex << ";";
std::cout << "amount:" << _amount << ";";
std::cout << "closed" << ";" << std::endl;
}
例で受け取ったlogと出力値が異なるので、少しクラッシュしました.スレイクといくつかのブログを見て、原因を知りました.簡単に言えば,システム仕様が異なるためmacではベクトル内の消失順序はバンプを実現した標準ライブラリに依存する.評価を忘れずに言ってください.
