c++ - 这有什么问题？ C++

Question

我正在尝试使用我所了解的 C++ 进行编程练习。它是一个基本的计算器，用于计算我玩的 MMO 的内容。

我想在不使用 system() 命令的情况下清除 cmd 的屏幕。但是在函数中:void clearscreen 第一个花括号在 vs 2013 中给出了一个错误，期望一个 ;

我也知道可能有更好的方法来完成所有这些，但这是我目前所知道的并且只是在练习。我主要想知道这有什么问题，但也非常感谢有关改进此基本程序的反馈

#include "stdafx.h"
#include <iostream>
#include <string>
#include <stdio.h>
#include <iomanip>

using namespace std;

int main()
{
    double timetotal;
    double timeperinv;
    double xptotal;
    double xpitem;
    double amount;
    double perinv;
    double totalinv;
    double costper;
    double costtotal;

    cout << "=+=+=+=+=+=+=+=Runescape Skill Calculator=+=+=+=+=+=+=+=" << endl;
    cout << endl;

    cout << "How much experience do you want to get?" << endl;
    cin >> xptotal;
    cout << endl;

    cout << "How much does it cost per item?" << endl;
    cin >> costper;
    cout << endl;

    cout << "How much experience do you get per item?" << endl;
    cin >> xpitem;
    cout << endl;

    cout << "How many items can you process in one inventory?" << endl;
    cin >> perinv;
    cout << endl;

    cout << "How long does it take to process one inventory of items?" << endl;
    cin >> timeperinv;

    amount   = xptotal / xpitem;
    totalinv = amount / perinv;
    timetotal = totalinv * timeperinv;
    costtotal = amount * costper;

    void ClearScreen()
    {
        cout << string(100, '\n');
    }

    cout << "=+=+=+=+=+=+=+=Runescape Skill Calculator=+=+=+=+=+=+=+=" << endl;
    cout << endl;
    std::cout << std::setprecision(1) << fixed;
    cout << "The amount of items that you will need to process is: \n" << amount << endl;
    cout << endl;

    cout << "The amount of inventories of items that you will need" << endl;
    cout << "to process is \n" << totalinv << endl;
    cout << endl;

    cout << "The total time it will take to complete processing all" << endl;
    cout << "of the items is: \n" << timetotal << endl;
    cout << endl;

    cout << "The total cost of the items will be: \n" << costtotal << endl;
    cout << endl;

    cout << "The total amount of inventories to process is: \n" << totalinv << endl;
    cout << endl;

}

C++ 不支持内部函数。只需在 main() 和 之外定义 ClearScreen。
