Question

我被告知要建立一个名为comparison（）的函数来比较两个财务计划。这两个财务计划在他们自己的职能部门中完美运作。如何调用compare（）函数中的两个函数？

这是第一份财务计划的代码。

void oneLumpSumWithdrawal( int startingAge, int numOfYears,
                           double lumpSumAmount, double interestRate )
{
    int age = startingAge;
    int lastAge = startingAge + numOfYears;
    double cash = lumpSumAmount;
    cout << "Age | oneLumpSum" << endl;
    cout << "----+----------------" << endl;
    while (age <= lastAge)
        cout.width(3);
    cout << age << " | ";
    cout.width(15);
    cout.precision(2);
    cout.setf(ios::fixed);
    cout << cash << endl;
    if (age != lastAge)
        cash = cash + cash*interestRate / 100.0;
    age++;

    system("pause");
}

这是第二个财务计划的代码

void yearlyWithdrawal(int startingAge, int numOfYears, int yearlyAmount, double interestRate)
{
    int age = startingAge;
    int lastAge = startingAge + numOfYears;
    double cash = yearlyAmount;
    cout << "Age | Yearly Plan" << endl;
    cout << "----+----------------" << endl;
    while (age <= lastAge)
    {
        cout.width(3);
        cout << age << " | ";
        cout.width(15);
        cout.precision(2);
        cout.setf(ios::fixed);
        cout << cash << endl;
        if (age != lastAge)
        {
            cash = (cash + cash*interestRate / 100.0) + yearlyAmount;
            age++;
        }
    }
    system("pause");
}

我试着这样称呼它，但它没有用。

void comparison()
{
  oneLumpSumWithdrawal( startingAge, numOfYears,
                            lumpSumAmount,  interestRate );

  yearlyWithdrawal(int startingAge, int numOfYears, int yearlyAmount, double interestRate);


}

用户将在main函数内的switch语句中调用该函数。

您正在致电

yearlyWithdrawal(int startingAge, int numOfYears, int yearlyAmount, double interestRate);

但是在调用函数时不必包含类型。你必须致电

yearlyWithdrawal( startingAge, numOfYears, yearlyAmount, interestRate);

如何调用另一个函数内的函数？ C ++
