IntelliSense:函数调用中的参数太少

IntelliSense: too few arguments in function call

本文关键字:参数 函数调用 IntelliSense      更新时间:2023-10-16

我正在为一个类编写一个程序,该类获取销售额并计算美元的变化。每个面额都以硬币数量作为输出列出。由于参数太少的错误,我无法运行它?

我不确定VB在这里找什么。如有任何帮助,我们将不胜感激。

程序代码:

#include <iostream>
#include <string>
#include <sstream>
#include <iomanip>
#include <cmath>
using namespace std;
// Determines how many of each coin to dispense.
void Dispenser(int, int *, int *, int *, int *);                                    

int main(void)
{
    // Change the console's background color.
    system ("color F0");
        // Declares the variables.
        double amount_paid = 1.00, amount_due;                                                             
        int amount_left, dollar_qty, quarter_qty, dime_qty, nickel_qty, penny_qty; 
    // Get user input.
    cout << "n";
    cout << "Enter the money amount paid: $";
        cin >> amount_due;
    cin.ignore();
    // Perform calculations.
    amount_paid = amount_paid * 100 + 0.5;
        amount_due = amount_due * 100;
        amount_left = amount_paid - amount_due;
        dollar_qty = amount_left / 100;
        Dispenser (amount_left + quarter_qty + dime_qty + nickel_qty + penny_qty);
        "n";

        // Display output.
        cout << "nAmount of the purchase: " << fixed << setprecision(2) << showpoint        << amount_due;
        cout << "nChange from $1.00: " << fixed << setprecision(2) << showpoint <<      amount_left;
        cout << "n" << fixed << setprecision(2) << showpoint << dollar_qty << "      dollars";
        cout << "n" << fixed << setprecision(2) << showpoint << quarter_qty <<       "quarters";
        cout << "n" << fixed << setprecision(2) << showpoint << dime_qty << "dimes";
        cout << "n" << fixed << setprecision(2) << showpoint << nickel_qty <<      "nickles";
        cout << "n" << fixed << setprecision(2) << showpoint << penny_qty <<      "pennies";
    system("pause");
        return 0;   
}
void Dispenser(int amt_left, int *quarters, int *dimes, int *nickels, int *pennies)
{
    int    total_change, total_quarters, total_dimes, total_nickels, total_pennies;
    // Determine change amount by quantity.
    total_change = amt_left % 100;
    total_quarters = total_change / 25;
    total_change = total_change % 25;
    total_dimes = total_change / 10;
    total_change = total_change % 10;
    total_nickels = total_change / 5;
    total_change = total_change % 5;
    total_pennies = total_change;
    *quarters = total_quarters;
    *dimes = total_dimes;
    *nickels = total_nickels;
    *pennies = total_pennies;
}

错误出现在"("的这一行

Dispenser (amount_left + quarter_qty + dime_qty + nickel_qty + penny_qty);
Dispenser (amount_left + quarter_qty + dime_qty + nickel_qty + penny_qty);

应该是

Dispenser (amount_left, quarter_qty, dime_qty, nickel_qty, penny_qty);

您的版本实际上只是一个将所有值相加的大参数,而我提供的带有逗号的版本意味着它是5个单独的参数发送到函数。

Dispenser (amount_left + quarter_qty + dime_qty + nickel_qty + penny_qty);

应该是

Dispenser (amount_left, &quarter_qty, &dime_qty, &nickel_qty, &penny_qty);

您使用了'+'而不是','?
